Jean-Daniel Cryans resolved HBASE-1654.
---------------------------------------
Resolution: Duplicate
I fixed this in HBASE-2189.
> client is broken, it requests .META.,,1 region location too much
> ----------------------------------------------------------------
>
> Key: HBASE-1654
> URL: https://issues.apache.org/jira/browse/HBASE-1654
> Project: Hadoop HBase
> Issue Type: Bug
> Reporter: stack
>
> In below, we fail to find a region because its not deployed yet. We get a
> NSRE. So, we retry but on retry we push the .META.,,1 region out of the
> cache. That seems wrong. Why is regetting .META.,,1 going to make a
> difference?
> Maybe its for case where .META. is made of multiple regions. Opening this
> issue to ensure that is indeed the case. Otherwise, below is wasted effort.
