Eric Payne commented on YARN-10613: ----------------------------------- I don't think the unit test failures were related. It looks like a build environment issue. This is from the UT log: {panel:title=https://ci-hadoop.apache.org/job/PreCommit-YARN-Build/671/artifact/out/patch-unit-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-server_hadoop-yarn-server-resourcemanager.txt} [INFO] Results: [INFO] [WARNING] Tests run: 2161, Failures: 0, Errors: 0, Skipped: 8 ...
