Hi @Joel Hatcher,

as the exception indicates topology already exists why dont you go kill the topology and try to start it again.

the syntax for storm CLI will be

storm kill topology-name [-w wait-time-secs]

That fixed the startup, but ambari still show it as not running. The storm ui shows that it is running, but it does not appear to be bug Ambari-1451 as I already have requests version 2.6.1 installed. Any ideas? Thank you for your help.ambari-agent.txt

Hi @Joel Hatcher ,

Glad that metron is started now.

Can you please accept the answer so that it will help other community users to understand the correct answer.

and for your Ambari showing wrong Metron status, can you confirm whats status in ambari-server.log , attached ambari-agent gives no data about the status .

you can check in ambari-server.log and look out for log's from class

ServiceResourceProvider

The ambari server log indicates that indexing is running.
