Question

Hadoop configuration || Unable to get index server information for client

I have configured a Hadoop backup in Commvault. The scan phase completes successfully and files are being detected correctly.

However, before the backup starts, the job fails with the following error:

"Unable to get index server information for client [120]"

Because of this, the backup never starts. I have waited for a long time, but no events or additional logs are being generated.

Environment details:

Hadoop client installed with required packages

MediaAgents are already configured

Communication services appear to be running fine

Has anyone faced this issue before? Any suggestions on what to check or how to resolve it would be really helpful.

    Hi ​@Laxman.Puvvalla  

    Confirm the Index Server is online if so in Hadoop subclient properties check if the correct index server is selected ensure the Hadoop client and MA can communicate with the Index Server on ports ( 8400, 8403, 20000) It is very difficult to identify the issue without reviewing the logs so I recommend opening a support case 

    Thanks and Regards,
    Mohammed Ramadan
