---------------------------------------
Summary: LLAP: MiniTez tez_join_hash test on the branch fails with
NPE
Key: HIVE-11013
URL: https://issues.apache.org/jira/browse/HIVE-11013
Project: Hive
Issue Type: Sub-task
Reporter: Sergey Shelukhin
Assignee: Matt McCline
Line numbers are shifted due to logging; the NPE is at
{noformat}
hashMapRowGetters = new ReusableGetAdaptor[mapJoinTables.length];
{noformat}
So looks like mapJoinTables is null.
I added logging to see if they could be set to null from cache, but that
doesn't seem to be the case.
Looks like initializeOp is not called.
