fstime of image file newer than fstime of editlog
-------------------------------------------------
Key: HDFS-2748
URL: https://issues.apache.org/jira/browse/HDFS-2748
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.20.2
Reporter: Denny Ye
1.1 first shutdown, then restart and then the fsimage was loaded and saved to
disk and editlog was cleared.
1.2 shutdown again when in safe mode to make sure no change in editlog, then
restart and then the fsimage was loaded and save to disk again, but the editlog
was not refreshed because it was empty.
1.3 shutdown again when in safe mode to make sure no change in editlog, the
restart and then an ERROR printed in log which basically was saying fstime of
fsimage was larger then fstime of editlog (which was obviously caused by saving
fsimage again and again when no change in editlog), and then the editlog would
be discarded (this is OK, the editlog was empty), and current fsimage would be
loaded as the latest fsimage. And again save fsimage.
