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.
