Siyao Meng commented on HDFS-13101:
-----------------------------------
[~shashikant] I found that the updated unit test `testDoubleRename` (was
`testFSImageCorruption`) since patch v3 doesn't reproduce the corruption
anymore. I tested that even if [L742-747 and
L754|https://github.com/apache/hadoop/blob/0a85af959ce505f0659e5c69d0ca83a5dce0a7c2/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/snapshot/DirectoryWithSnapshotFeature.java#L742-L747]
is commented out, the new unit test won't catch the corruption. But the old
unit test in v2 WILL. I might file another jira to improve the unit test.
> Yet another fsimage corruption related to snapshot

> Lately we saw case similar to HDFS-9406, even though HDFS-9406 fix is
> present, so it's likely another case not covered by the fix. We are currently
> trying to collect good fsimage + editlogs to replay to reproduce it and
> investigate.
