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).
