Enis Soztutar commented on HBASE-12035:
---------------------------------------

Great to get this committed. Shouldn't we undo all the changes that is to do 
keeping the table state in hdfs. The PB structures and HTD changes are 
deprecated, but we've never had a release out having them, so we should just 
clean those up I think.

> 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.
