Hi, I'm running Hadoop 2.7.1 release. While I'm running a MapReduce job, I've encountered a file permission issue as shown below because I'm working in an environment running Linux where world permissions bits are disabled.
2016-10-14 15:51:45,333 INFO org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ResourceLocalizationService: Writing credentials to the nmPrivate file /state/partition1/hadoop/nm-local-dir/nmPrivate/container_1476470591621_0004_02_000001.tokens. Credentials list: 2016-10-14 15:51:45,375 WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ResourceLocalizationService: Permissions incorrectly set for dir /state/partition1/hadoop/nm-local-dir/usercache, should be rwxr-xr-x, actual value = rwxr-x--- Does any one have any suggestions to work around the issue for a single user environment, where one user can running all the services and run the Map-reduce jobs? I'm not familiar with the source code but if you suggest me where to modify to relax the check, it would be appreciated. Thanks, - Chansup
