I'm having some ETL queries that I put in oozie workflow.
However, from time to time (30% of cases) I get a Java Heap Memory. In the rest of the cases I have a sucessful result.
I never run multiple workflows in the same time so there should be exactly the same process runing.
Where should I look in order to solve this? I tried to increase the java heap for clients/ for metastore. Still the same thing.
