Hi [~manojg], I was looking at the test case to understand the problem better.
The test passes for me even without the fix in INodeFile (I ran the new test
against git hash 2ee0d64aceed876f57f09eb9efe1872b6de98d2e).
Do you see the test fail without the fix?

bq. I cherry-picked to 3.0.1.
https://hadoop.apache.org/versioning.html defines the commit flow. Since the
commit was done to trunk and branch-2, we need to make sure the branches in the
middle are committed too. 3.0.1 is great, but we also need branch-3.0. I just
did it but please try your best to commit to necessary branches.
Thanks a lot.

Hi [~yzhangal] thanks for the review. Would you please take a further look to
see if the fix is applicable to 3.0.1, 2.8.x and older branches?
Thanks

Above unit test failures are not related to the patch. Will take care of the
