------------------------------------
Summary: Hive tez bucket map join conversion interferes with map
join conversion
Key: HIVE-6828
URL: https://issues.apache.org/jira/browse/HIVE-6828
Project: Hive
Issue Type: Bug
Components: Tez
Affects Versions: 0.13.0, 0.14.0
Reporter: Vikram Dixit K
Assignee: Vikram Dixit K
The issue is that bucket count is used for checking the scaled down size of the
hash tables but is used later on to convert to the map join as well which may
be incorrect in cases where the entire hash table does not fit in the specified
size.
