I try to deactivate a topology from Storm UI but It gives me the following error in a popup.
Error while communicating with Nimbus.
I have tried my chance from the command line with the following:
[root@sandbox-hdp ~]# storm deactivate WordCountTopology
But not a chance. Gives the following error:
Exception in thread "main" org.apache.storm.thrift.transport.TTransportException
@Erkan ŞİRİN you might be hitting this bug: https://issues.apache.org/jira/browse/STORM-860
Do run the "storm list" command and check if the status is same.
