BELUGA BEHR created HIVE-19403:
----------------------------------
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.
