Jonathan Hung commented on YARN-9529:
-------------------------------------

Thanks! This was when reconfiguring 
{{yarn.nodemanager.linux-container-executor.cgroups.hierarchy}}. The previous 
log prints this dir's parent dir which was never writable, so the NM should 
never have been able to start up. But it's checking the writability of this 
configured dir (not its parent), hence the logging change.

> Log correct cpu controller path on error
