ElasticsearchException: Failure running machine learning native code - elasticsearch

i am learning Elasticsearch and tried to install it on my windows 8 (64 bit) machine.
firstly i tried to install in using zip file downalod elasricsearch
but that didn't worked for me, the command prompt gets closed after this
after that i tried installing elasticsearch using windows installer (MSI).
but i ended up having this
i found one cause for this error on internet that environment is not 64bit but in my case it is..please give me some sollution.

you can append a config line
xpack.ml.enabled: false
in config file ${elastic_search_home}/config/elasticsearch.yml to bypass this problem.

In case you run in Docker container you can disable machine learning functionality setting environment variable -e "xpack.ml.enabled=false".

For Mac Users
On OSX installed with Homebrew
Add: xpack.ml.enabled: false
To: /usr/local/etc/elasticsearch/elasticsearch.yml
And restart: brew services restart elastic/tap/elasticsearch-full

Not able to convert existing WSL1 distro to WSL2

I have installed Ubuntu-18.04 on my Windows 10 (Build 19041 which meets the requirements for WSL2) and am trying to convert this distro into WSL2. I have been following this guide.
To do so, I run the following command in Windows PowerShell:
wsl --set-version Ubuntu-18.04 2
But I get the following error after a few minutes:
This operation returned because the timeout period expired.
I have tried different networks (fearing it was a firewall issue) but to no avail. Any idea how to fix this?
Make sure you have the linux kernel update package installed. Then, run wsl --set-default-version 2 to set the default WSL version to WSL2.

Docker for Desktop error during connect: Post A connection attempt failed because the connected party did not properly

I have freshly installed Docker for Desktop Edge in Windows 10 Home and try to build an image using the docker build command. But unfortunately, it didn't work for me, and got the below error :
CMD - docker build -t heet1996/post:0.0.1 .
error during connect: Post https://192.168.99.100:2376/v1.40/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&session=na8ugnpn6d8gnxl3z8ppx4gap&shmsize=0&t=heet1996%2Fpost%3A0.0.1&target=&ulimits=null&version=1: dial tcp 192.168.99.100:2376: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Earlier I was using a docker toolbox so I had to remove all the environment variables related to the Docker in my User variables before installing Docker for Desktop. After a lot of search on GitHub issues, I am still not getting the solution.
This is what I found in my service.txt file (C:\ProgramData\DockerDesktop\service.txt)
[18:27:22.232][LoggingMessageHandler][Info ] [f9b6b957] <Server end> POST http://localhost/dns/refresh-hosts -> 204 NoContent (took 118ms)
I got this error when i un-installed the docker toolbox and installed the docker desktop.
System Configuration:
OS: Windows 10 Home
Version: 21H1
Steps I Followed:
Un-installed the docker desktop.
Removed the all dockers related environment variables from the user variables.
Navigation: This System-> Properties-> Advance System Settings-> Environment Variables-> User Variables.
Re-installed the docker desktop and it's started working properly.
Try to run it on Docker CLI instead of CMD
Open Powershell as Administrator and run the below commands
cd "C:\Program Files\Docker\Docker"
./DockerCli.exe -SwitchDaemon
Docker for windows must have:
[✓] Updated Windows 10 version >=2004
[✓] WSL 2 and Default Distro (i.e ubuntu)
The steps are well documented here. These are what to do after the installation:
To confirm ubuntu's installation, open C:/Windows/System32/bash.exe aka bash.
To test if docker is properly installed, run docker version on bash. This should print the docker client and server engine.
After successfully tested and confirmed the installations, try entering your command
$ docker build -t heet1996/post:0.0.1 .
here we are talking about using Docker with PowerShell and not with WSL. And also following the addition of variables in the environment variables of Windows.
Configuration when this response was made:
Windows 10 Pro 20H2 (Build 19042.867)
Docker 20.10.5
Powershell 5.1.19041.610
I also had to configure docker in a dirty way too much, after several hours of research and a comparison of installation on a clean Windows 10 I understood where my error was.
In addition to the user environment variable also make sure that you do not have DOCKER variables in the Windows system environment variables either.
Here is where my error was, I think it was due to the installation of the Docker module
I had the DOCKER_HOST variable in my system variable environment, so i deleted it.
If you want to check all your environment variables with Powershell:
[System.Environment]::GetEnvironmentVariables()
If you really want a Docker fresh installation on Windows, you need to delete the following folders:
C:\ProgramData\Docker
C:\Program Files\Docker\Docker
$HOME\AppData\Local\Docker
$HOME\AppData\Roaming\Docker
$HOME\AppData\Roaming\Docker Desktop
$HOME\.docker
my error, therefore, produced this error:
ERROR ==> error during connect: Get http://docker.artofshell:2376/v1.24/version: dial tcp: lookup docker.artofshell: no such host
After a complete uninstall of all docker (Via chocolatey, official docker ...) and by properly installing Docker from the official executable here everything is back to normal
Then if you want to use docker via Powershell you have to change the configuration of DockerCLI as you can see on many answers
Conclusion
It is possible to use docker with Powershell you must check if the
server daemon is used by Windows/amd64, you can modify the daemon with this command cd "C:\Program Files\Docker\Docker"; .\DockerCli.exe -SwitchDeamon
You can check the configuration of the daemon with the following command: docker version
You must remove all traces of old Docker installations if you had any
You must delete the environment variables from the old installation or from the docker toolbox
You must also activate the experimental features: information here

Having trouble getting docker to work on mac

OK so here is what I have done so far. I installed docker for mac, and that worked fine. From there I tried to get a project up and running using docker-compose and I got the following error:
Could not read CA certificate "/Users/<useraccountfolder>/.boot2docker/certs/boot2docker-vm/ca.pem": open /Users/<useraccountfolder>/.boot2docker/certs/boot2docker-vm/ca.pem: no such file or directory
So I tried to fix it by trying this accepted answer. This is when I got another error, Host does not exist: “default”. This is when I trie this accepted answer, but when I tried to run docker-machine create default, I got this error: Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path". I am just lost at this point. Any help?
To use docker machine you need the latest version of VirtualBox, from the docker docs:
IF YOU ARE USING DOCKER FOR MAC
Docker for Mac uses HyperKit, a lightweight macOS virtualization solution built on top of the Hypervisor.framework in macOS 10.10 Yosemite and higher.
Currently, there is no docker-machine create driver for HyperKit, so you will use virtualbox driver to create local machines. (See the Docker Machine driver for Oracle VirtualBox.) Note that you can run both HyperKit and Oracle VirtualBox on the same system. To learn more, see Docker for Mac vs. Docker Toolbox.
Make sure you have the latest VirtualBox correctly installed on your system (either as part of an earlier Toolbox install, or manual install).
Source: https://docs.docker.com/machine/get-started/#prerequisite-information
OK so I found a solution which is probably not fixing the root issue, but it does work. To unset previous variables I ran this command unset ${!DOCKER*}. This worked, but then I had to run it every time I started a new terminal session, so I added it to my .bash_profile and now I am good.

Pycharm docker remote python interpreter

When trying to configure a Remote Python Interpreter in Pycharm using Docker I get the following error:
com.github.dockerjava.api.excepion.DockerClientException: Enabled TLS
verification (DOCKER_TLS_VERIFY=1) but certificate path
(DOCKER_CERT_PATH) '/Users/me/.docker/machine/machines/default'
doesn't exist.
I've $export DOCKER_TLS_VERIFY=0 but with no difference.
I've manually created '/Users/me/.docker/machine/machines/default' but with no joy.
I've deinstalled and reinstalled both Docker and Pycharm but still get the same error.
I'm on a Mac OSX 10.12.1
Pycharm 2016.3
Full disclosure: I use vagrant and virtual box on my mac too.
Any pointers would be appreciated.
Kevin
I fixed it as follows:
Obtain socat (if not already installed)
e.g. brew install socat
Then: socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock
Then in pycharm/docker config:
Api URL: tcp://localhost:2375
Many thanks to the following found on:
https://youtrack.jetbrains.com/issue/IDEA-153973
If you have been using docker-machine for Mac to support PyCharm or the "socat" hack to access Docker API - It is no longer necessary with PyCharm EAP (https://www.jetbrains.com/pycharm/nextversion/) — You can set your remote debugger API_URL directly to: unix:/var/run/docker.sock (supporting debug mode, and the environment runs a lot faster, when not using VirtualBox).
There is a no-questions-asked 30 day trial of EAP before that update goes live (some time this month)

Why Rethinkdb don't have binary for windows?

I am interested in Rethinkdb and would like to develop/test on it, but main problem is: it don't have package for windows operating system. I tried to compile from source code, that was also not possible as there was no any instruction.
What makes it so difficult to make executable for windows? Is there any alternative way to install Rethinkdb in windows OS? even very small and not that famous application has windows binary but not Rethinkdb. It is quite surprise for me. Another surprising is there are many community executable for other OS but not windows.
Thank you for understanding and waiting for good answer.
Rethinkdb just announced that it started development for Windows. Please follow
[1] https://github.com/rethinkdb/rethinkdb/issues/1100
[2] https://twitter.com/segphault/status/590633792781611009
Update:
RethinkDB announced in Windows :
[3] https://rethinkdb.com/docs/install/windows/
Cross-platform development isn't that easy. RethinkDB uses some features under the covers which makes porting it to Windows a difficult job, f.e. a Unix toolchain for the builds and Unix syscalls. For more information on that have a look at this GitHub issue. It states that Windows support is planned, but with low priority.
As a quick fix, you could RethinkDB run in a virtual machine or in Microsoft Azure. For the second one, I wrote a blog post a few weeks ago.
RethinkDB has already started development for Windows. While it's not released yet, this is how you can run it through Vagrant. See: https://github.com/gearz-lab/rethinkdb-vagrant
I'm using Chocolatey, feel free to skip steps if they don't apply.
Installing Chocolatey
Open Powershell as an administrator and run this command:
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
... now you should have Chocolatey installed. We're gonna use to install the others.
Installing Vagrant
Run this as an administrator:
choco install vagrant -y
Installing VirtualBox
Vagrant relies on a virtualization application that it calls a "provider". The default one is VirtualBox so let's install it. Run cmd as administrator and run this:
choco install virtualbox -y
Now you should be able to run the vboxmanage command. If it doesn't work, make sure C:\Program Files\Oracle\VirtualBox is in your PATH.
Installing Cygwin
We're gonna log on a virtual machine using SSH, so we need a SSH enabled terminal. For that, let's use Cygwin.
choco install cyg-get -y
Installing Cygwin packages
There'are two Cygwin packages we need to install, openssh, because Cygwin doesn't have SSH support by default, and rsync so Vagrant can use it to synchronize files between the host and the guest machines.
On PowerShell, running as an administrator, let's run these commands:
cyg-get openssh
cyg-get rsync
Cloning rethinkdb-vagrant
Open the Cygwin64 Terminal. You should now be in your Cygwin home folder, which should look like C:\tools\cygwin\home\[YOUR_USER].
Make sure you have git installed. If you don't just choco install git -y. Now, clone rethyinkdb-vagrant:
git clone https://github.com/gearz-lab/rethinkdb-vagrant.git
Now you should have a directory like this: C:\tools\cygwin\home\[YOUR_USER]\rethinkdb-vagrant.
Starting Vagrant and useful commands
From inside the Cygwin64 Terminal home directory (described in the last step), type cd rethinkdb-vagrant, now, any Vagrant commands will target cd rethinkdb-vagrant.
To setup and boot the machine: vagrant up (After this, RethinkDB is available, see next step).
To access the machine's terminal: vagrant ssh.
To destroy the machine (every RethinkDB data will be lost): vagrant destroy.
To suspend the machine: vagrant suspend.
To resume a suspended machine: vagrant resume.
Accessing RethinkDB.
Make sure you have vagrant up from the last step. Now:
For accessing the web administration tool: http://localhost:8080.
For accessing RethinkDB from a client app, the port is 28015.
