----------------------------------
Summary: Skip setting up hive scratch dir during planning
Key: HIVE-21182
URL: https://issues.apache.org/jira/browse/HIVE-21182
Project: Hive
Issue Type: Improvement
Reporter: Vineet Garg
Assignee: Vineet Garg
During metadata gathering phase hive creates staging/scratch dir which is
further used by FS op (FS op sets up staging dir within this dir for tasks to
write to).
Since FS op do mkdirs to setup staging dir we can skip creating scratch dir
during metadata gathering phase. FS op will take care of setting up all the
dirs.
