Thank you very much akhil .I did the same process and it was working fine.My concern is that ,i need to stop my application which is streaming process if i want to remove any host .This will lead to down time for my application and as we know storm is a streaming process i will lose my data at that point of time.So is there any other way where my storm application will run smoothly and parallelly i can remove host also.

I am trying to delete one host from 2 node hortonworks cluster by using following steps: 1) I stopped all the services from selected host which were running.from Hosts tab > Host Actions > Stop All Components. 2) Stopped ambari agent from selected host. 3) Then click Host Actions > Delete Hosts. But i am not able to delete the host .It is showing that " Unable to Delete Host Deletion of the following 2 components is not supported. DRPC Server, Storm UI Server" When i deleted the storm service it worked fine. So is any there other way for removing host where we need not to delete the services like storm ,metrics collector,grafana etc ?.if we are using service like storm it is mandatory to stop the service?. please suggest solution for that.
