I have series of hive actions in a oozie workflow and I am getting the same error everyday in or the other hive actions. I have attached the logs of the job which failed. Please help me resolve it.

Running it on CDH 5.9.1 . Have set following global parameters in workflow.xml as well :

Hi ,

The error message suggested that HS2 was not running, have you confirmed by connecting from beeline to make sure that you can run queries through the HS2?

Hi Eric

Yes I am able to connect to HS2. Moreover, most of my queries are dealing with huge data so the execution time is also high. Most of the days it fails in on or the other hive actions.

Also, other jobs including hive action are working fine.

In that case, my suggestion is to check for HS2 logs to try to find any queries that takes time to compile. Because HS2 currently can only compile one query at a time, if you have a query that takes a while to compile, it will lock out HS2 and other requests will have to wait.

I am not sure if it is the cause, but worth to check the HS2 log. Look for the following example:

Completed compiling command(queryId=hive_20170227192424_ee0c5216-bef5-456a-934e-212aabe55b75); Time taken: 0.191 seconds

and check if any Time taken values are too big around the time when issue happens.
