---------------------------------------
Summary: MapJoinBytesTableContainer dummyRow case doesn't handle
reuse
Key: HIVE-20787
URL: https://issues.apache.org/jira/browse/HIVE-20787
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
Discovered while investigating some (probably) unrelated issue.
MapJoinBytesTableContainer was not intended to be reused, but it looks like
some code might reuse it. If that happens, the dummyRow case will not work
correctly (dummyRow is cleared on first(), so another call to first() will
behave differently).
