[jira] [Created] (IMPALA-14736) Enable tcmalloc's aggressive_memory_decommit in catalogd

Abhishek Rawat created IMPALA-14736:
---------------------------------------

             Summary: Enable tcmalloc's aggressive_memory_decommit in catalogd
                 Key: IMPALA-14736
                 URL: https://issues.apache.org/jira/browse/IMPALA-14736
             Project: IMPALA
          Issue Type: Task
            Reporter: Abhishek Rawat


Catalogd doesn't return its page heap freelist to the OS. As a result, when catalogd is configured with a small process memory limit, it may encounter OOM if the JVM heap plus tcmalloc heap together exceed the process limit.
