Mikhail Antonov commented on HBASE-11759:
-----------------------------------------
There's another jira (linking) where table state is proposed to be moved out of
ZK completely, to be permanently saves inside HTableDescriptor, and cached in
memory inside TableStateManager. What do you think?
> TableZnode should be cached

> Observed on 0.98 with zk less assignment.
> On receiving the rpc call about Region state transition, the rpc reader
> threads on master tries to figure whether the table is in disabling or
> disabled state. For this they all read tableznode which becomes a point of
> contention. We can just cache the state of table.
