--------------------------------------
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.
