Storm UI RuntimeException

aaron_harris — Wed, 12 Oct 2016 16:32:08 GMT

Am running the full-dev environment single node VM for Metron, after restarting the node and starting the services through Ambari there were some issues with Storm. I cleared out the storm.local.dir and restarted which seems to have allowed all the Storm services to start through Ambari, but when I access the web UI for Storm there is an internal server error.

java.lang.RuntimeException: Could not find leader nimbus from seed hosts ["node1"]. Did you specify a valid list of nimubs hosts for config nimbus.seeds.

I have tried restarting zookeeper but am not sure how to clear out the zookeeper configuration in Metron environment.

Any help would be greatly appreciated.

@Aaron Harris

Couple of things to check.

1 ] Can you please confirm whether nimbus service is up and running

2] Check for error in nimbus log available on nimbus host at path /var/log/storm/nimbus.log

3] Check for error in storm ui log available at storm ui server at path /var/log/storm/ui.log

@Santhosh B Gowda

Thanks for your response.

Nimbus is showing as running without errors in Ambari and the service looks to be up correctly.

I am getting an error in the nimbus.log as below;

Actually I have found a section further up in the log that might be the actual error;

2016-10-13T08:08:54.289+0000 b.s.zookeeper [INFO] node1 gained leadership, checking if it has all the topology code locally.

Fixed now thanks, the issue was that I had backed up my storm local data previously because of an issue with the supervisor starting.

Once I copied the nimbus/stormdist folder back into the storm local data folder and started nimbus again it all came up correctly.
