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

             Summary: Client does an RPC to master everytime a region is 
relocated
                 Key: HBASE-12035
                 URL: https://issues.apache.org/jira/browse/HBASE-12035
             Project: HBase
          Issue Type: Improvement
            Reporter: Enis Soztutar
             Fix For: 2.0.0


HBASE-7767 moved table enabled|disabled state to be kept in hdfs instead of 
zookeeper. isTableDisabled() which is used in 
HConnectionImplementation.relocateRegion() now became a master RPC call rather 
than a zookeeper client call. Since we do relocateRegion() calls everytime we 
want to relocate a region (region moved, RS down, etc) this implies that when 
the master is down, the some of the clients for uncached regions will be 
affected. 

See HBASE-7767 and HBASE-11974 for some more background.
