stack commented on HBASE-12035:
-------------------------------
I like 1-4 in above. Are you suggesting that RS implement M protocol and it
would answer questions about table schema? That seems confusing. Rather, I
like the idea that RS keeps warm knowledge of 'table' state so can be font for
table state rather than have clients ping pong off master. Good stuff.
> Client does an RPC to master everytime a region is relocated

>
> 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.
