Jason Lowe updated YARN-5482:

Assignee: tangshangwen (was: Jason Lowe)
This is really more of a duplicate of YARN-5341 since this was reported against
2.7. It's fixed in 2.7.4. Backporting YARN-5296 could also fix the issue but
causes other problems, hence why we fixed it specifically for 2.7 in YAN-5341.
