>   // If not parseable as region name, presume encoded. TODO: add stringency; e.g. if hex.
>   return parseRegionNameOrReturnNull(regionName) == null && regionName.length <= MD5_HEX_LENGTH;

> Right now, if it passes in an table name, it still thinks  it is a encoded region name and will result in unnecessary registry query for meta regions. This can be avoided if table names can be filtered out early in this method.{code}
