Hi, I got this error when browsing Storm UI: org.apache.storm.utils.NimbusLeaderNotFoundException: Could not find leader nimbus from seed hosts ["dev-dob1-tmon-machine-01.foo.dns.com" "dev-dob1-tmon-machine-02.foo.dns.com" "dev-dob1-tmon-machine-03.foo.dns.com"]. Did you specify a valid list of nimbus hosts for config nimbus.seeds? at org.apache.storm.utils.NimbusClient.getConfiguredClientAs(NimbusClient.java:111)
And in the nimbus log I see many of these lines: 2019-09-05 14:27:35.921 o.a.s.d.nimbus timer [INFO] not a leader, skipping assignments 2019-09-05 14:27:35.921 o.a.s.d.nimbus timer [INFO] not a leader, skipping cleanup My guess is the data in Zookeeper may got corrupted, since it worked yesterday for nimbus running on another VM, but I have destroyed the VM, so maybe it still thinks already-gone node is the leader, and stuck. Is there a way to safely reset the Storm data in Zookeeper? If yes, which znodes should I delete? Thanks, Z
