> Its a problem because commonly a check for existence will get list of current
> tables.
> Yesterday saw problem when .META. went off line. A piece of client code was
> asking for list of tables when .META. was offline, it was getting back an
> empty list because listTables do while was seeing
> 'org.apache.hadoop.hbase.NotServingRegionException: .META.,,1'
> Problem is the do while in HCM.listTables goes as long as startRow does not
> equal LAST_ROW but startRow is initialized with EMPTY_START_ROW which is
> equal to LAST_ROW.
