---------------------------------------
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.
