----------------------------------

             Summary: Demote 'Pattern' Logging
                 Key: HIVE-19403
                 URL: https://issues.apache.org/jira/browse/HIVE-19403
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 3.0.0, 2.4.0
            Reporter: BELUGA BEHR


In the {{DDLTask}} class, there is some logging that is not helpful to a cluster admin and should be demoted to _debug_ level logging.  In fact, in one place in the code, it already is.

{code}
LOG.info("pattern: {}", showDatabasesDesc.getPattern());
LOG.debug("pattern: {}", pattern);
LOG.info("pattern: {}", showFuncs.getPattern());
LOG.info("pattern: {}", showTblStatus.getPattern());
{code}

Here is an example... as an admin, I can already see what the pattern is, I do not need this extra logging.  It provides no additional context.

{code:java|title=Example}
