I have installed Cassandra Version: 2.2.3 in windows 10. When I cqlsh command in the prompt I get the following -
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 2.2.3 | CQL spec 3.3.1 | Native protocol v4]
Use HELP for help.
WARNING: pyreadline dependency missing. Install to enable tab completion.
I have installed pyreadline using pip install pyreadline and it installed successfully.
I have restarted the system as well but couldn't get rid of that warning.
Any help is highly appreciated.
You could try adding your python to your PATH environment variable. Maybe thats why you may be having that problem.

The recommended method for installing orion-ml is via pip (e.g., pip install orion-ml) as stated in the github README.md
However, this simple command causes the error

ERROR: Cannot install orion-ml because these package versions have conflicting dependencies.
The conflict is caused by:

mlprimitives 0.2.3 depends on tensorflow<2 and >=1.11.0
mlprimitives 0.2.2 depends on tensorflow<2 and >=1.11.0
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

This tells us there is a version conflict. How can I resolve this? Thank you
I ran into the same issue and found out that orion-ml only worked with Python >=3.6, <3.8, but I had Python 3.9.2 installed which ended up pullig orion-ml 0.1.0 which is a very old version. I uninstalled 3.9.2 and installed a version under Python 3.8 and it worked
Install Anaconda:
https://www.anaconda.com/products/individual#download-section
Create a virtual environment with python version 3.7.(3.8.8 python makes an error installing "pip install orion-ml")
Run your python 3.7 virtual env.
pip install orion-ml : There's no error install "orion-ml" package.
Create a separate conda environment like:
conda create --name orion python=3.7 # or 3.6
conda activate orion
and then install tensorflow using:
pip install https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.8.0-py3-none-any.whl
This will get you rid of the tensroflow error.
I am trying to install SAP/BUILD from GitHub. But I could not find a way to install it. There is no proper guides available online for installation. So please guide me.

making sure that you create a directory for the dbms, using the default C:\data\db or an alternate one as described.
1.1. Install NodeJs v0.10.38
test the install with the cmdline
node --version
returns
v0.10.38
1.2 Install SapBuild with npm:
npm install -g sap-build-cli#0.3.3
1.3 Start MongoDB as per above document
1.4 Start SapBuild (node daemon running)
1.5 Go to Chrome Browser and type the url

That's it.
I'm setting up a HDP 2.1 cluster with Apache Ambari. All servers run SLES 11 SP3. The setup fails if I select to install Ganglia because of some dependencies:
Installing package apache2?mod_php* ('/usr/bin/zypper --quiet install --auto-agree-with-licenses --no-confirm apache2?mod_php*')
Problem: apache2-mod_php53-5.3.17-0.27.1.x86_64 conflicts with apache2-mod_php5 provided by apache2-mod_php5-5.2.14-0.7.30.50.1.x86_64
Solution 1: Following actions will be done:
do not install apache2-mod_php5-5.2.14-0.7.30.50.1.x86_64
deinstallation of php5-5.2.14-0.7.30.50.1.x86_64
deinstallation of php5-xmlwriter-5.2.14-0.7.30.50.1.x86_64
[... more PHP 5.2.x packages ...]
Solution 2: do not install apache2-mod_php53-5.3.17-0.27.1.x86_64
Apparently the Regex picks the 5.3 version, a 5.2 version would be available though.
So my question is: Where is the install script stored, that Ambari is running here? I would like to replace the regex with the correct version of the package.
Information about what packages are to be installed is stored in
/var/lib/ambari-server/resources/stacks/HDP/2.0.6/services/GANGLIA/metainfo.xml
Change the value and restart the Ambari Server for the changes to take effect.
I've been trying to get past step one of installing grails, which is bad i know. But the issue im having is getting grails to work via the OSX terminal. similar to node using brew I type the command
brew install grails
this retrieves grails and installs it, simple. to see if its installed correctly you type grails -version
However when i do that it's as though my terminal restarts. Its a hard thing to describe so here is a link to a youtube video that shows you what happens. I have JAVA installed and working. Anyone have an idea?
https://www.youtube.com/watch?v=ButLwGfBTZo
As this is the first excursion I have had into any Java related development. I made a rookie mistake and was unaware of vital piece of information. You do not need Java to run Grails you need the Java Development Kit (JDK). Which is a different thing completely apparently.
Available here
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Once installed run this command in the terminal /usr/libexec/java_home -V This will show you all of the current Java Virtual Machines installed. In my case
Matching Java Virtual Machines (1):
1.8.0_11, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home
You then need to set your JAVA_HOME Environment variable to point to your JVM. Like so export JAVA_HOME=$(/usr/libexec/java_home) use /usr/libexec/java_home rather than the true location as this will specifi the version set in Java Preferences for the current user. The source for that nice little trick is here http://www.mkyong.com/java/how-to-set-java_home-environment-variable-on-mac-os-x/
Once you've done that you can type the command brew install grails or gvm install grails which is what i should probably use rather than brew as "SurrealAnalysis" rightly pointed out in one of the answers.
moment of truth grails -version and i got a response Grails version: 2.4.3... sweet.
Thank you all for the replies and help.
Following previous post, GVM it is not available in Homebrew, because of this.
GDK is also now officially SDKMAN!.
So, the steps would be:
curl -s "https://get.sdkman.io" | bash
source "/Users/{YOUR_USER_NAME}/.sdkman/bin/sdkman-init.sh"
sdk install groovy
Hope it helps! :)
I just spun up a machine on EC2 running Cassandra following the instructions in the link below, but I have no idea what version it is. How do I figure this out? I know I'm missing something incredibly simple, just don't know where to look.

It might be easier to use nodetools
./nodetool -h localhost version
You could use cqlsh.
$ cqlsh
Connected to Test Cluster at localhost:9160.
[cqlsh 3.1.8 | Cassandra 1.2.18 | CQL spec 3.0.5 | Thrift protocol 19.36.2]
Use HELP for help.
May also use "SHOW VERSION" command in CQL:
cqlsh:mydb> SHOW VERSION ;
[cqlsh 5.0.1 | Cassandra 2.1.2 | CQL spec 3.2.0 | Native protocol v3]
After reviewing the instructions you listed, it looks like you're on a Debian(-based) system. In particular, in the "Cassandra Basic Setup" section, it says:
Step 3. Install the Debian package for Cassandra
% apt-get update % apt-get install cassandra
At this point, Cassandra will be installed and running. However, it's not configured for a multi-node cluster. So we need to continue.
If you followed this step to install Cassandra, you can simply use Debian's package management tool to inquire about the package you installed:
% dpkg -s cassandra
Try the describe_version() method.
http://wiki.apache.org/cassandra/API#describe_version
You could query your package manager:
dpkg -l cassandra
or
yum info cassandra
Go to Cqlsh command prompt and type show version to get the version of cassandra you are using
