Here are steps to move SHS from one node to another. Replace admin:admpw with your user-name:password. Run on the Ambari server, or replace localhost with your Ambari server FQDN. Replace "mycluster" with your cluster name. Replace host2.example.com with your target node FQDN. Delete SHS component (it looks like you already did this so you can skip this step) $ curl -i -H "X-Requested-By:ambari" -u admin:admpw -X DELETE http://localhost:8080/api/v1/clusters/mycluster/services/SPARK/components/SPARK_JOBHISTORYSERVER Add SHS again $ curl -i -H "X-Requested-By:ambari" -u admin:admpw -X POST http://localhost:8080/api/v1/clusters/mycluster/services/SPARK/components/SPARK_JOBHISTORYSERVER Install host component on the new node: host2.example.com $ curl -i -u admin:admpw -H "X-Requested-By:ambari" -i -X POST -d '{"host_components" : [{"HostRoles":{"component_name":"SPARK_JOBHISTORYSERVER"}}] }' http://localhost:8080/api/v1/clusters/mycluster/hosts?Hosts/host_name=host2.example.com In Ambari, Hosts --> host2.example.com, click on Spark History Server, and then "Reinstall" button In Ambari-->Spark, start Spark service, and run Spark service check ...

Yes, you can combine services on the same master, including HA instances and search apps. You just try to distribute them so that all 3 masters are about equally busy. Here is one layout: M1: Ambari, AMS Collector, Hue, Oozie M2: NN1, RM1, ATS, Spark History Server, Spark Thrift Server, SOLR M3: NN2, RM2, MR2 JHS, Hive HS2 + Metastore + DB, ES with Zookeepers and Journal nodes on all 3 masters. If you want to test SOLR and ES extensively you may wish to place them on the 4th master. If you want to add more services (HBase, Falcon, Atlas), just distribute their master components on available masters. ... View more

It looks like your app cannot locate HBase master and/or Region Servers, meaning that you haven't provided HBase configuration. Here are some examples how to do that. ... View more
