[jira] [Created] (IMPALA-5802) COMPUTE STATS uses MT_DOP=4 by default

Alexander Behm created IMPALA-5802:
--------------------------------------

             Summary: COMPUTE STATS uses MT_DOP=4 by default
                 Key: IMPALA-5802
                 URL: https://issues.apache.org/jira/browse/IMPALA-5802
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend, Frontend
    Affects Versions: Impala 2.9.0
            Reporter: Alexander Behm


Now that IMPALA-3905 has been completely addressed we should run COMPUTE STATS with MT_DOP=4 by default, regardless of file format. The motivation is consistency and speeding up COMPUTE STATS in most cases.

This task is a continuation of IMPALA-4572.
