Date Thu, 06 Dec 2018 10:26:00 GMT
Guanghao Zhang created HBASE-21560:
--------------------------------------

             Summary: Return a new TableDescriptor for MasterObserver#preModifyTable to allow
coprocessor modify the TableDescriptor
                 Key: HBASE-21560
                 URL: https://issues.apache.org/jira/browse/HBASE-21560
             Project: HBase
          Issue Type: Improvement
            Reporter: Guanghao Zhang


Same with HBASE-21550. The new TableDescriptor is immutable for 2.0+. But in our use case,
the coprocessor may change the TableDescriptor when preModifyTable. It is allowed before 2.0.
For 2.0+, We can return a new TableDescriptor for MasterObserver#preModifyTable to allow
this.
