Hi @PCP2 , can you clarify which HDP/CDH/CDP version are you using?

Is this a one-off or an intermittent issue or does it always happen? 
Is this affecting only a single job? What kind of an action is Oozie trying to launch?

Thanks, Miklos

[#3]

Hi @mszurap , we are using CDP version 7.1.7, this is an intermittent issue, encountering twice a week. 

This is a single job(ingestion) where we are processing files(parquet) using shell scripts. Insertion of these files will go through map reduce. 

[#4]

Can you review the whole logfile? The above NPE may be just a side effect of another failure before.

[#5]

We dont have much information in logs. we refer stderr logs...PFA logs for the failed instance.

[#6]

@PCP2 Were you able to get any leads on this issue ? 

[#7]

@PCP2 @Krisssh Hello, we cannot work out such issues through a community post, we recommend to open a case to look in detail for each case. Thanks!
