Subject [jira] [Created] (HIVE-5110) Investigate memory consumption during map-side join
Date Fri, 16 Aug 2013 16:08:47 GMT
Brock Noland created HIVE-5110:

             Summary: Investigate memory consumption during map-side join
                 Key: HIVE-5110
             Project: Hive
          Issue Type: Improvement
            Reporter: Brock Noland

In map-side join we have this track the JVM memory usage and if it's over a certain limit
we fail the task. In HIVE-4838 we discussed removing that and letting the JVM run OOM. However
there was a concern that this could cause performance problems for queries that will run out
of memory.

This jira is to decide we can let the JVM run OOM and if so remove that check. If we cannot,
can we raise the default limit?
