ATTACHMENT ID: 12640286
> Hive unable to find the hashtable file during complex multi-staged map join
> ---------------------------------------------------------------------------
>
> Key: HIVE-6913
> URL: https://issues.apache.org/jira/browse/HIVE-6913
> Project: Hive
> Issue Type: Bug
> Reporter: Brock Noland
> Assignee: Brock Noland
> Attachments: HIVE-6913.patch
>
>
> If a query has multiple mapjoins and one of the tables to be mapjoined is
> empty, the query can result in a "no such file or directory" when looking for
> the hashtable.
> This is because when we generate a dummy hash table, we do not close the
> TableScan (TS) operator for that table. Additionally, HashTableSinkOperator
> (HTSO) outputs it's hash tables in the closeOp method. However, when close is
> called on HTSO we check to ensure that all parents are closed:
> https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/Operator.java#L333
> which is not true on this case, because the TS operator for the empty table
> was never closed.
