[jira] [Created] (HIVE-16151) BytesBytesHashTable allocates large arrays

Sergey Shelukhin created HIVE-16151:
---------------------------------------

             Summary: BytesBytesHashTable allocates large arrays
                 Key: HIVE-16151
                 URL: https://issues.apache.org/jira/browse/HIVE-16151
             Project: Hive
          Issue Type: Bug
            Reporter: Prasanth Jayachandran
            Assignee: Sergey Shelukhin


These arrays cause GC pressure and also impose key count limitations on the table. Wrt the latter, we won't be able to get rid of it without a 64-bit hash function, but for now we can get rid of the former.
