             Summary: Miscellaneous improvements in driver compile and execute 
logging
                 Key: HIVE-12713
                 URL: https://issues.apache.org/jira/browse/HIVE-12713
             Project: Hive
          Issue Type: Improvement
          Components: Logging
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang
            Priority: Minor


Miscellaneous compile and execute logging improvements include:
1. ensuring that only the redacted query to be logged out
2. removing redundant variable substitution in HS2 SQLOperation
3. logging out the query and its compilation time without having to enable 
PerfLogger debug, to help identify badly written queries which take a lot of 
time to compile and probably cause other good queries to be queued (HIVE-12516)
