We have spark 1.0.2 cluster with 3 nodes under HA setup using zookeeper. We have long running self contained spark service that serves on-demand requests. I tried to do failover test by killing spark master and see if our application get ported over to new master. Looks like killing master doesn't really kills executors that were created by application. So our application is still able to serve request but problem is I can no longer see our applicaiton running in UI. Probably just issue of not having a history server ? Driver UI still works. Can someone confirm this? I am also attaching screenshot of new master console that display "Running Application" section
