NodeManager puts YARN_CONTAINER entities with CPU and MEMORY metrics but this
is not shown in above output. Found NM container entries are updated with right
flowRunId (startTime of the job) whereas RM container entries are updated with
default 0. TimelineReader fetches only rows which are updated by RM (i.e,
rowkeys with flowRunId 0).
