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.
