> 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.
