I have installed HDP2.7.5. but When I start the yarn & hdfs Service.I have encountered the following problems.
The following error was encountered while trying to retrieve the URL:
http://n15hdp02:50070/webhdfs/v1/tmp?
Unable to determine IP address from host name n15hdp02
The DNS server returned:
Name Error: The domain name does not exist.
This means that the cache was not able to resolve the hostname presented in the URL. Check if the address is correct.
Your cache administrator is root.

I am trying to start a chainlink node in rinkeby testnet.I have setup a postgres DB in AWS. The Database URL is already given. Below is the error while i am trying to start the node.

I tried changing few settings from AWS front but nothing helped.. If anyone have any clue pls help me up.
Based on the documentation it looks like there may be an "s" in front of your postgres URL, try removing that in your .env file. Also try replacing the database name with the IP address+Port. What should replace $DATABASE is "postgres". Finally try adding in ?sslmode=disable if you don't have ssl activated at the database (not recommended for a production node).
Example in .env:
DATABASE_URL=postgresql://me1234:password1234#10.10.100.100:3000/postgres?sslmode=disable
my website is no longer accessible. When I try to load my plesk file manager, im presented with the following error below.
Internal error: filemng failed: Unable to lookup SID for name TestWebSite: (1332) No mapping between account names and security IDs was done. (Error code 1)
I believe i'm on shared hosting so I can't RDP to the server. Any idea's what other options I have or how to resolve this issue/
Fix it in CLI with following commands:
"%plesk_dir%\bin\repair.exe" --repair-webspace-system-users -webspace-name example.com
"%plesk_dir%\bin\repair.exe" --repair-webspace-security -webspace-name example.com
I am trying to create a MAPR cluster, nut I have DNS inconsistent warning. I have edited my /etc/hosts file as
10.0.0.10 master.aptus.com
10.0.0.20 slave1.aptus.com
10.0.0.30 slave2.aptus.com
These system contribute to establishing cluster. When i execute :
host 10.0.0.10
the output is:
10.0.0.10.in-addr.arpa has no PTR record
And when I execute :
host master.aptus.com
I get the following output :
master.aptus.com has address 128.199.41.186
I tried to run the installation with warning, but installation fails.
MAPR installation fails
Update DNS entry in domain server
Update the DNS server (AD server) with the new ip address for the cluster node which is being migrated. Once it is updated, all the nodes in the cluster will be able to resolve it.
Check the reverse lookup zone and make sure it is the same using dns tool or ssh
Try it let me know if it helps.
I'm attempting to set up a test environment where the software is being developed on host machines then tested in a Virtual Machine and the VM has all code mapped to a Z:/ drive. My issue is that Apache is complaining and won't start up saying that I have an invalid Include path of Z:/source/myconf.conf. Anyone have luck previously of setting conf files up in a different different drive path that can help me understand what I'm doing wrong? I've tried with and without quotes as well.
Include path statement:
Include "Z:/source/myconf.conf"
Additional info:
Z is a virtual drive through VMWare also known as \\vmware-host
The specific error in the Application logs is as follows:
The Apache service named reported the following error:
httpd.exe: Syntax error on .. of C:/.../httpd.conf: Invalid Include path Z:/source/myconf.conf
Seems like its finding issue connecting to the Z drive and as z is the network drive, it must require user name and password which is creating issue
solution
If we can save the user name and password so that it won't ask for user credential dbl clicking to z drive.
To save permanently the user credential
Open command prompt and type
"net use Z: \servername\sharename /persistent:yes /savecred"
Now restart and see it should not ask user credential to connect to z drive and the apache error won't be there.
I have installed Chef server on One Physical Linux node successfully,
Now i am trying to install chef-client on the other Linux VM,
Unfortunately i am getting below error.
ERROR: Your private key could not be loaded from /etc/chef/webui.pem
Check your configuration file and ensure that your private key is readable
so copied the webui.pem from chef server to Linux Client
tried to execute knife client List
ERROR: Failed to authenticate to http://xxx.xxx.xxx.xxx:4000 as admin with key /etc/chef/webui.pem
Response: Failed to authenticate. Ensure that your client key is valid.
To use knife you need to be logged in as an admin user. Either copy down the servers admin.pem key or better still create a new admin user and use its key.
Another thing to fix is make sure the node_name used to login matches the key you're using. (The error message suggests you're using "admin"):
node_name 'myuser'
client_key '/home/me/.chef/keys/myuser.pem'
