[jira] [Created] (HDFS-17021) GENSTAMP_MISMATCH replica can not be removed by invalidateCorruptReplicas()

Shuyan Zhang created HDFS-17021:
-----------------------------------

             Summary: GENSTAMP_MISMATCH replica can not be removed by invalidateCorruptReplicas()
                 Key: HDFS-17021
                 URL: https://issues.apache.org/jira/browse/HDFS-17021
             Project: Hadoop HDFS
          Issue Type: Bug
         Environment: If a replica is corrupted due to generation stamp mismatch, the corresponding datanode stores a wrong generation stamp while `invalidateCorruptReplicas()` will send right generation stamp to the datanode.  Therefore, the check on datanode can not pass successfully as discussion in [https://github.com/apache/hadoop/pull/5643.] resulting in the corrupted replica unable to be successfully deleted.
