----------------------------
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.
