Please visit http://gerrit.cloudera.org:8080/5315 to look at the new patch set (#4). Change subject: IMPALA-4572: Run COMPUTE STATS on Parquet tables with MT_DOP=4. ...................................................................... IMPALA-4572: Run COMPUTE STATS on Parquet tables with MT_DOP=4. COMPUTE STATS on Parquet tables is run with MT_DOP=4 by default. COMPUTE STATS on non-Parquet tables will run without MT_DOP. Users can always override the behavior by setting MT_DOP manually. Setting MT_DOP to 0 means a statement will be run in the conventional execution mode (without intra-node paralellism based on multiple fragment instances). Users can set a higher MT_DOP even for Parquet tables. Testing: Added a new test that checks the effective MT_DOP. Locally ran test_mt_dop.py, test_scanners.py, test_nested_types.py, test_compute_stats.py, and test_cancellation.py.
