---------------------------------
Summary: Integer overflow bug in
ConditionalResolverCommonJoin.AliasFileSizePair
Key: HIVE-5418
URL: https://issues.apache.org/jira/browse/HIVE-5418
Project: Hive
Issue Type: Bug
Affects Versions: 0.11.0
Reporter: Steven Wong
Sometimes, auto map join conversion unexpectedly fails to choose map join over
a common join, even if the auto map join conversion's size criterion is
satisfied.
This is caused by an integer overflow bug in the method {{compareTo}} of the
class {{ConditionalResolverCommonJoin.AliasFileSizePair}}.
The bug can be triggered when the big table size exceeds the small table size
by at least 2**31 bytes.
