Daniel Templeton commented on YARN-5301: ---------------------------------------- My concern was that swallowing the exception might leave things in a bad state. I tested on MacOS, and it looks like everything works out in the end. My one final quibble, though, is that the comment about unit tests is a little misleading. I just exercised this code path by running a node manager on MacOS, not through a unit test. > NM mount cpu cgroups failed on some systems > ------------------------------------------- > > Key: YARN-5301 > URL: https://issues.apache.org/jira/browse/YARN-5301 > Project: Hadoop YARN > Issue Type: Bug > Reporter: sandflee > Assignee: Miklos Szegedi > Attachments: YARN-5301.000.patch, YARN-5301.001.patch, > YARN-5301.002.patch, YARN-5301.003.patch, YARN-5301.004.patch, > YARN-5301.005.patch, YARN-5301.006.patch > > > on ubuntu with linux kernel 3.19, , NM start failed if enable auto mount > cgroup. try command: > ./bin/container-executor --mount-cgroups yarn-hadoop cpu=/cgroup/cpu fail > ./bin/container-executor --mount-cgroups yarn-hadoop cpu,cpuacct=/cgroup/cpu > succ -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
