[jira] [Created] (HBASE-11653) RegionObserver coprocessor cannot override KeyValue values in prePut()

Gary Helmling created HBASE-11653:
-------------------------------------

             Summary: RegionObserver coprocessor cannot override KeyValue values in prePut()
                 Key: HBASE-11653
                 URL: https://issues.apache.org/jira/browse/HBASE-11653
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
    Affects Versions: 0.94.21
            Reporter: Gary Helmling
            Assignee: Gary Helmling
            Priority: Critical


Due to a bug in {{HRegion.internalPut()}}, any modifications that a {{RegionObserver}} makes to a Put's family map in the {{prePut()}} hook are lost.

This prevents coprocessors from modifying the values written by a {{Put}}.
