Joe Witt commented on NIFI-6882:
--------------------------------
+1 merged to master after fixing/removing tests that cause build failures due
to not being able to clean up properly and happening outside target dir.
Thanks for the contrib. Please do use PRs or patches with full author

Manually verified the failure on an old build and the success on a new build
with this commit.
