             Summary: WALProcedure may remove proc wal files still with active procedures
                 Key: HBASE-21490
                 URL: https://issues.apache.org/jira/browse/HBASE-21490
             Project: HBase
          Issue Type: Sub-task
          Components: proc-v2
            Reporter: Duo Zhang


It happens for me several times. After master restart, all the procedures are gone.

And the proc wal files were deleted before restarting, I see this in the master's log
