------------------------------------
Summary: Correctly enforce the memory limit on the multi-table
map-join
Key: HIVE-3996
URL: https://issues.apache.org/jira/browse/HIVE-3996
Project: Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 0.11.0
Reporter: Vikram Dixit K
Assignee: Vikram Dixit K
Currently with HIVE-3784, the joins are converted to map-joins based on checks
of the table size against the config variable:
hive.auto.convert.join.noconditionaltask.size.
However, the current implementation will also merge multiple mapjoin operators
into a single task regardless of whether the sum of the table sizes will exceed
the configured value.
