Subject [jira] [Created] (HIVE-5836) Improve logging in ExecReducer.reduce()
Date Sat, 16 Nov 2013 01:49:20 GMT
Hari Sankar Sivarama Subramaniyan created HIVE-5836:

             Summary: Improve logging in ExecReducer.reduce()
                 Key: HIVE-5836
             Project: Hive
          Issue Type: Bug
            Reporter: Hari Sankar Sivarama Subramaniyan
            Assignee: Hari Sankar Sivarama Subramaniyan
             Fix For: 0.13.0

Although ExecReducer.reduce() logs the used JVM heap memory, we need to log the committed,
max and used memory (
to debug any future outofmemory issues.

  "ExecReducer: processing " + cntr
                + " rows: used memory = " + used_memory);
i.e. the above log info should include max_memory as well as committed_memory for a propery
analysis of memory usage at runtime.
