    • Type: Improvement
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 3.0.0-alpha-1, 2.2.0
    • Component/s: Coprocessors
    • Labels:
      None
    • Hadoop Flags:
      Incompatible change
    • Release Note:
      Incompatible change. Allow MasterObserver#preModifyTable to return a new TableDescriptor. And master will use this returned TableDescriptor to modify table.

      Description

      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.
