------------------------------------
Summary: Splits grouping is optional
Key: HIVE-6718
URL: https://issues.apache.org/jira/browse/HIVE-6718
Project: Hive
Issue Type: Improvement
Components: Tez
Affects Versions: 0.14.0
Reporter: Vikram Dixit K
In hive-tez, we are always grouping splits in case of bucket map joins. This
can be made optional. This affects utilization of the cluster as it affects
parallelism. In some cases, it could be better to turn off grouping for
increased parallelism as well. Making it optional gives better control to the
administrator.
