Masatake Iwasaki commented on YARN-10347:
-----------------------------------------
Thanks, [~ayushtkn]. I'm running {{mvn test}} in
hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager
on my local. I will commit the patch after checking the result.
Since I can reproduce the docker failure by running ./start-build-env.sh, I
filed HADOOP-17120.
