> NodeManager puts YARN_CONTAINER entities with CPU and MEMORY metrics but this
> is not shown in above output. Found NM container entities are set with
> entityIdPrefix as inverted container starttime whereas RM container entities
> are set with default 0. TimelineReader fetches only RM container entries.
> Confirmed with setting NM container entities entityIdPrefix to 0 same as RM
> (for testing purpose) and found metrics are shown.
