> 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).
