Yiqun Lin updated HDFS-11696:
-----------------------------
Attachment: HDFS-11696.005.patch
Attach the updated patch to fix the new generated warnings.
One note:
In the line {{super.visitFile(file, attrs);}} in
{{NNUpgradeUtil#doPreUpgrade}}, If input file is null, it will throw NPE
inside. In order to fix findbus issue, I do this outside to keep the consistent
logic.
