> As I written in AMBARI-22632, yarn.py wrongly sets 755 permission to
> '/ats/done' and '/ats/active' by default. This is because the default value
> of yarn.timeline-service.entity-group-fs-store.done-dir is '/ats/done/' and
> the default value of yarn.timeline-service.entity-group-fs-store.active-dir
> is '/ats/active/', and both of the default value have trailing '/'.
> Next yarn.py sets 700 permission to the directories, so finally the
> permissions become correct.
> This issue causes redundant WebHDFS calls every time when launching ATS.
