Description

When is set parameter 'fs.permissions.umask-mode' with value 0002

org.apache.hadoop.fs.FileContext always use internally 0022.

After investigation found that org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ResourceLocalizationService->serviceInit(Configuration conf) sets always FsPermission.DEFAULT_UMASK value.

@Override
  public void serviceInit(Configuration conf) throws Exception {
    this.validateConf(conf);
    this.publicRsrc =
        new LocalResourcesTrackerImpl(null, dispatcher, true, conf);
    this.recordFactory = RecordFactoryProvider.getRecordFactory(conf);

    try {
      FileContext lfs = getLocalFileContext(conf);
      lfs.setUMask(new FsPermission((short)FsPermission.DEFAULT_UMASK));

      cleanUpLocalDir(lfs,delService);
