Subject [jira] [Commented] (TEZ-3741) Tez outputs should free memory when closed
Date Thu, 01 Jun 2017 15:32:04 GMT

Kuhu Shukla commented on TEZ-3741:
----------------------------------

Thanks [~jlowe] for the updated patch!

I should have caught this sooner but may be we need a similar change for PipelinedSorter (SortSpan.close())
for completeness. Thoughts?

Also, 
{code}
 boolean isClosed() {
    return kvbuffer == null && kvmeta == null;
  }
{code}

Do we want it marked as @VisibleForTesting or have it available for other src/main files in
the package?

> Memory buffers aren't being released as quickly as they could be, e.g.: DefaultSorter
is holding onto the very large kvbuffer byte array even after close() is called, and Ordered
and Unordered outputs should remove references to sorter and kvWriter in their close.
