Change subject: IMPALA-8097: mt_dop for all queries via hidden flag
......................................................................
IMPALA-8097: mt_dop for all queries via hidden flag
--unlock_mt_dop=true unlocks mt_dop for all queries
including joins and inserts.
This disables the parallel plans with separate join builds
when running standalone, because these are not executable.
Inserts work without modification - they were disabled
because of lack of testing and the possibility for
generating many small files with unpartitioned inserts.
Testing:
Add custom cluster test that exercise joins, runtime filters
and inserts as a sanity check for the flag.
Ran exhaustive build.
Manually ran TPC-H and TPC-DS tests against a minicluster
with mt_dop = 4.
