[jira] [Created] (HIVE-20041) ResultsCache: Improve loggng for concurrent queries

Gopal V created HIVE-20041:
------------------------------

             Summary: ResultsCache: Improve loggng for concurrent queries
                 Key: HIVE-20041
                 URL: https://issues.apache.org/jira/browse/HIVE-20041
             Project: Hive
          Issue Type: Improvement
          Components: Diagnosability
            Reporter: Gopal V


The logging for QueryResultsCache ends up printing information without context, like 

{code}
2018-06-30T17:48:45,502  INFO [HiveServer2-Background-Pool: Thread-166] results.QueryResultsCache: Waiting on pending cacheEntry
{code}

{code}
2018-06-30T17:50:17,963  INFO [HiveServer2-Background-Pool: Thread-145] ql.Driver: savedToCache: true
{code}

The previous lines for this are in DEBUG level, so the logging ends up being useless at INFO level to debug.
