@Saurabh Kumar Metrics for which you are trying to generate the graph needs to be edited manually. Enter "metrics/yarn/Queue/root/AvailableMB" in metric box while selecting Resourcemanager Similarly for child queue of root viz child1 you have to enter metrics/yarn/Queue/root/child1/AvailableMB I have tested this on ambari Version 2.2.0.0 with hdp stack 2.3.4.0.

@Kunal Gaikwad You have to use same key pair on all the hosts.

What is your ambari and HDP version. Try generating graph for some other component like Resourcemanager. Also try deleting stale hosts/services from ambari.

@Saurabh Kumar Ensure that you select values from drop-down list. You don't need to add values manually. Also ensure that you don't miss any value

Did you get anything on running grep -ir dev2 /etc/yum.repos.d ?

@Prakash Have you tried using internal ip instead? Please give it a shot if not already done.

@Duminda Jayasuriya My understanding is it is always a good idea to have separate server for JournalNodes and zookeepers in production environment with HA. Also for cost-effectiveness JournalNodes and zookeepers can be co-hosted. Co-hosing comes with the prize of downtime of all services which are co-hosted. Both zookeeper and JournalNodes are quorum based system. Co-hosting them with master nodes will give only 2 nodes, rest of the nodes should be hosted on separate machines.

Try configuring your environment using internal ip address(10.0.7.1) instead of 192.168.25.x one

AFAIK there is no stop action for spark-client or any client for that matter. Client means set of libraries for using the associated service. @Artem Ervits, please correct if I am missing something.

Edit /usr/hdp/2.3.2.0-2950/oozie/bin/oozie.distro and add below line before line 59 to see what value JAVA_BIN is taking. This may happen if you have updated/reinstalled Java and script is referring to old path. echo ${JAVA_BIN}
