Review request for Ambari, Sumit Mohanty and Sid Wagle. Repository: ambari Description ------- Noticed that there are no HDFS / YARN metrics sent to AMS. HBase and host metrics are all ok. There was a time where due to lack of resources AMS HBase was not keeping up with the writes and customer had to reconfigure to get it to work. Although after restarting AMS only the host and HBase metrics start showing. Note: Historical AMS data still exists for HDFS and YARN, which means the Sinks were operational for some time.
