Zhijie Shen commented on MAPREDUCE-5768:
----------------------------------------
I've observed a number of jenkins builds in this month that have the same
failure, for example,
* https://builds.apache.org/job/PreCommit-YARN-Build/3198/
* https://builds.apache.org/job/PreCommit-YARN-Build/3087/
* https://builds.apache.org/job/PreCommit-YARN-Build/3078/
* https://builds.apache.org/job/PreCommit-YARN-Build/3160/
* https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1701/
* https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1707/
Therefore, I'm guessing it is a reproducible test failure.
