Probably a noob query!
I wanted to know if there was any real impact on a functioning cluster if the ambari-server service is stopped. Say for example all the services like Yarn, HBase, etc are running and there are multiple jobs based of spark or flink running on the cluster and the ambari-server is stopped.
Other than the cluster monitoring not a possibility, does it really affect the execution of Flink/Spark jobs or the ability to access data from HDFS or HBase?
Stopping the Ambari server wont effect the other service like HDFS,Zookeeper etc provided you used the CLI, the other components and the daemons are independent and will continue to run in the background what you only lose is the Visual view of the cluster status ,running the below java command
will show the major components runing evenif Ambari is down
$ ambari-server stop/start
The Ambari server role is management and deployment of the cluster,
Thanks for your answer.
So there's no issue if the agents are unable to report their status to the server? I was wondering if the nodes would be out of sync somehow since it's unable to communicate with the server and ingorm it's alive.
