> I noticed the following log entries where localization was being retried on
> several MR AM files.
> {code}
> 2018-02-02 02:53:02,905 INFO
> org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.LocalResourcesTrackerImpl:

> is missing, localizing it again
> {code}
> The cluster is configured to use LCE and
> {{yarn.nodemanager.linux-container-executor.nonsecure-mode.local-user}} is
> set to a user ({{hadoopuser}}) that is in the {{hadoop}} group. The user has
> a umask of {{0002}}. The cluser is configured with
> {{fs.permissions.umask-mode=022}}, coming from {{core-default}}. Setting the
> local-user to {{nobody}}, who is not a login user or in the {{hadoop}} group,
> produces the same results.
> {code}
> [hadoopuser@y7001 ~]$ umask
> 0002
> [hadoopuser@y7001 ~]$ id
> uid=1003(hadoopuser) gid=1004(hadoopuser) groups=1004(hadoopuser),1001(hadoop)
> {code}
> The cause of the log entry was tracked down a simple !file.exists call in
> {{LocalResourcesTrackerImpl#isResourcePresent}}.
> {code}
> public boolean isResourcePresent(LocalizedResource rsrc) {
> boolean ret = true;
> if (rsrc.getState() == ResourceState.LOCALIZED) {
> File file = new File(rsrc.getLocalPath().toUri().getRawPath().
> toString());
> if (!file.exists()) {
> ret = false;
> } else if (dirsHandler != null) {
> ret = checkLocalResource(rsrc);
> }
> }
> return ret;
> }
> {code}
> The Resources Tracker runs as the NM user, in this case {{yarn}}. The files
> being retried are in the filecache. The directories in the filecache are all
> owned by the local-user's primary group and 700 perms, which makes it
> unreadable by the {{yarn}} user.
> {code}
> [root@y7001 ~]# ls -la
> /hadoop-yarn/usercache/hadoopuser/appcache/application_1517540536531_0001/filecache
> total 0

> drwx------. 2 hadoopuser hadoopuser 61 Feb 2 03:05 10

> drwx------. 2 hadoopuser hadoopuser 41 Feb 2 03:06 13
> {code}
> I saw YARN-5287, but that appears to be related to a restrictive umask and
> the usercache itself. I was unable to locate any other known issues that
> seemed relevent. Is the above already known? a configuration issue?
