-----------------------------------
bump
> Storm UI and nimbus CLI not working
> -----------------------------------
>
> Key: STORM-3705
> URL: https://issues.apache.org/jira/browse/STORM-3705
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.2.1
> Reporter: Neha Gupta
> Priority: Major
>
> When deploying a topology on nimbus, there were errors in topology because of
> wrong configuration, due to which every request was failing in the topology.
> In our code, there is this logic that if a topology observes error more than
> a particular threshold, then it will issue storm deactivate topology command
> to nimbus.
> The restart of topologies was being done via script.
> The scenario was:
> 2 topologies were restarted successfully but facing errors due to wrong
> configuration. Because of the same, deactivate command was submitted to
> nimbus.
> 3rd topology was killed successfully and command for topology submission for
> the same was received successfully by nimbus.
> At this point, storm UI stopped responding completely. When tried to run kill
> command via CLI on nimbus, it didn't work either and stayed stuck.
> At this point, the 2 topologies with errors were still running as
> deactivation was not successful via nimbus. And the 3rd topology wasn't
> restarted via nimbus.
> Any other commands ran on nimbus, stayed at stuck state until the nimbus was
> stopped on the leader machine and another nimbus was made leader.
> There are no helpful logs in nimbus or supervisors or worker logs of affected
> topologies, apart from zookeeper info logs below:
> {color:#FF0000}zookeeper [INFO]
> exceptionorg.apache.storm.shade.org.apache.zookeeper.KeeperException$NoNodeException:
> KeeperErrorCode = NoNode for
> /errors/<AFFECTED-TOPOLOGY-ID>/<BOLTNAME-WITH_ERRORS>/e0000001494
> {color}Storm version: 1.2.1
