Thanks @susheelgupta7 for the fix! LGTM!

[brumi1024]

Thanks @susheelgupta7 for the patch, @K0K0V0K for the review, merging to trunk.

[brumi1024]

@susheelgupta7 can you please check if this applies to branches 3.3 and 3.4 and if yes backport the fix there as well? Thanks!

[susheelgupta7]

@brumi1024 I can't reproduce this issue on branch 3.3.0
This issue can be seen on branch-3.4.0 so created a pull request https://github.com/apache/hadoop/pull/7657/files
