Guang Yang commented on HBASE-15942:
------------------------------------

Thanks all for the comments.

I might be wrong, but at least for now, only the table schema would be exposed 
to caller once the validation passed (HMaster#getTableDescriptors), the details 
of HCD (including the encryption keys, etc) would not.

As [~andrew.purt...@gmail.com] pointed out, more information might get added to 
HTD and HCD, but if the contract that we only expose schema for the 
getTableDescriptors holds, I guess we are safe in that regard?

> User with 'RWX' permission of the table should be able to describe the table

> Currently only the user who has 'ADMIN' or 'CREATE' permission could describe 
> the table (via shell), it brings some inconvenience and confusion to those 
> uses who have RWX permission since they couldn't describe the table to get 
> the schema.
