The JIRA YARN-4610 links YARN-3434 <https://issues.apache.org/jira/browse/YARN-3434> as the one causing the breakage, and YARN-3434 already exists in 2.7.1 itself. That categorizes the new issue as an existing bug.
If you agree with that sentiment, and given that there is a clear work-around, in the interest of progress of 2.7.2 (we have spent > 2 months on this now), I’d like to move forward. Please LMK what you think.
