> *LogAggregationFileController.verifyAndCreateRemoteLogDir* tries to check
> whether the remote file system has set/modify permissions on the
> _yarn.nodemanager.remote-app-log-dir:_

> {code:java}
> //Check if FS has capability to set/modify permissions
> try {
> remoteFS.setPermission(qualified, new
> FsPermission(TLDIR_PERMISSIONS));
> } catch (UnsupportedOperationException use) {
> LOG.info("Unable to set permissions for configured filesystem since"
> + " it does not support this", remoteFS.getScheme());

> } catch (IOException e) {
> LOG.warn("Failed to check if FileSystem suppports permissions on "
> + "remoteLogDir [" + remoteRootLogDir + "]", e);

> But it will fail if the _yarn.nodemanager.remote-app-log-dir_'s owner is not

> Checking the set/modify permission could be done with a temporarily created
> file in the _yarn.nodemanager.remote-app-log-dir_. If the NM's user have
> permission to write in the directory (e.g.: because it is in the proper
> group) then creating the file with the NM's user would be usable for
> permission checking.
