> 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}
