Support team, Ther are couple of Impala queries running daily as part of a JenKins Job and are failing occassionally,with following errors.
Status: RPC Error ETIMEDOUT
here are the series of events in relevance.
I put a property on the Impala Side service earlier on the cloudera Manager to cover RPC Error ETIMEDOUT
But i still receive this error., below is the context to showcase the query.
Impala queries are Join intensive with multiple table joins.
I try to increase the Memory parameters, to make run for eg : from 35 gb to 50 GB. i am trying to find if there are any advance look out options from Cloudera Perspective to nail down,the root cause, if it is beyond memory parameters.
