Description

Our HBase client tries to get the HTable descriptor for a table that may or may not exist. We catch and ignore the TableNotFoundException if it occurs, but the log message appear regardless of this which confuses our users. Would it be possible to lower the log level of this message since the exception is already being throw (making it up to the caller how they want to handle this).
