Duo Zhang commented on HBASE-21550:
-----------------------------------
Since we only a new method into the MasterObserver, and for java 8 we have
default method for interface, I do not think it is an incompatible change. So
maybe we can also commit to branch-2.1 and branch-2.0? [~stack]
Also ping [~zghaobac].
> Add a new method preCreateTableRegionInfos for MasterObserver which allows
> CPs to modify the TableDescriptor

> Before 2.0, we will pass a HTableDescriptor and the CPs can modify the schema
> of a table, but now we will pass a TableDescriptor, which is immutable. I
> think it is correct to pass an immutable instance here, but we should have a
> return value for this method to allow CPs to return a new TableDescriptor.
