Hi Don, AMS is not a mission-critical service, so you can turn it off since no other Hadoop service depends on it. Why are you turning it off though?
It has far more improvements and optimizations in Ambari 2.4 Thanks, Alejandro From: Don Brinn <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Tuesday, December 6, 2016 at 1:54 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Dependencies on Ambari Metrics Service? Hi, Would there be any functional impact of turning off Ambari Metrics Service and leaving it off indefinitely, other than no longer having metrics that we can use to monitor the state of our Hadoop cluster? Is there anything within Ambari or the Hadoop cluster that depends on the metrics service? For example, would Ambari still be able to detect and report if some other node or service is down? I'm considering turning off the metrics service for a while but want to be sure that that will not break anything in the cluster. [This is with HBase version 0.98.4.2.2.6.0-2800-hadoop2 and Ambari Version 2.0.1.] Thanks, Don
