> 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.
