----------------------------

             Summary: Purger can remove stale fsimage ckpt files
                 Key: HDFS-3716
                 URL: https://issues.apache.org/jira/browse/HDFS-3716
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 2.0.0-alpha
            Reporter: suja s
            Priority: Minor


NN got killed while checkpointing in progress before renaming the ckpt file to actual file.
Since the checkpointing process is not completed, on next NN startup it will load previous fsimage and apply rest of the edits.
Functionally there's no harm but this ckpt file will be retained as is.
Purger will not remove the ckpt file though other old fsimage files will be taken care.
