[jira] [Created] (HBASE-21550) Should allow returning a modified TableDescriptor for MasterObserver.preCreateTable

Duo Zhang created HBASE-21550:
---------------------------------

             Summary: Should allow returning a modified TableDescriptor for MasterObserver.preCreateTable
                 Key: HBASE-21550
                 URL: https://issues.apache.org/jira/browse/HBASE-21550
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
            Reporter: Duo Zhang
             Fix For: 3.0.0, 2.2.0


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.
