Can you try running the insert query after changing execution engine to mr?

set hive.execution.engine=mr;

Thank you very much Sindhu!

It is working!

Re: Tez session hasn't been created yet. Opening session

@Daniela Boamba

That means the issue is with Tez alone not Resource Manager. Can you please check if the Tez client is installed or not?

Thanks and Regards,

Yes, it is.

@Daniela Boamba

Can you share Resource manager log and Hive server 2log for analysis?

This log is incomplete and doesn't help. Would you mind sharing the hive log when you trigger the same error? Your can share it via pastebin or collabedit.

Re: Tez session hasn't been created yet. Opening session

The problem could lie with not enough resources available for a Tez session to start. Could you run

yarn application -list

on a YARN client host and see if there are any processes hogging up resources or possibly check the configs and logs to make sure that Tez isn't just hanging and waiting for resources to become available.
