             Summary: 'not a leader' exception submitting topologies to LocalCluster
                 Key: STORM-3038
                 URL: https://issues.apache.org/jira/browse/STORM-3038
             Project: Apache Storm
          Issue Type: Bug
    Affects Versions: 1.2.1
            Reporter: Simon Cooper


In our local tests running on our openstack build servers, we get intermittent failures due to the following exception being thrown when submitting topologies to LocalCluster:

{code}275354 [main] WARN  o.a.s.d.nimbus - Topology submission exception. (topology name='AnalyseUpdate') #error {
 :cause not a leader, current leader is NimbusInfo{host='<hostname>', port=6627, isLeader=true}
 :via
 [{:type java.lang.RuntimeException
   :message not a leader, current leader is NimbusInfo{host='<hostname>', port=6627, isLeader=true}
   :at [org.apache.storm.daemon.nimbus$is_leader doInvoke nimbus.clj 150]}]

(note that {{isLeader=true}} in the exception message)

This is despite a retry mechanism we've implemented; this seems to be a continual failure, once its hit. This tends to be surrounded by lots of zookeeper connection lost/reconnection log message.
