-------------------------------------

             Summary: HBaseAdmin#deleteTable fails when META region happen to 
move around same time
                 Key: HBASE-10809
                 URL: https://issues.apache.org/jira/browse/HBASE-10809
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.96.1, 0.98.0, 0.99.0
            Reporter: Jeffrey Zhong


The issue is that in the retry loop, we never refetch the latest meta location. 
So if meta starts to move right after the function get Meta server location, 
the delete table eventually may fail with 
{code}org.apache.hadoop.hbase.NotServingRegionException: Region hbase:meta,,1 
is not online{code}
