Sangjin Lee commented on YARN-5379:
-----------------------------------
I saw it once yesterday with YARN-5364. Then this morning I saw another with
the trunk build report:
https://builds.apache.org/job/hadoop-qbt-trunk-java8-linux-x86/94/
I don't believe this is related to tests running concurrently.
