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.
