Andrey Stepachev commented on HBASE-11993:
------------------------------------------
May be it is better to merge TableStateManager and FSTableDescriptors. Seems
that there is two caches maintained and need to be kept in sync?
> Expose the set of tables available in TableStateManager

> TableStateManager has the full set of TableNames already in memory,
> we should expose the set of table names and use it instead of going to query
> the fs descriptors.
> (Is there any reason why we don't have the descriptors in-memory too? saving
> memory with tons of tables? do we even support tons of tables?)
