             Summary: If a drpcserver node in cluster is down,drpc cluster won't work is we don't modify the drpc.server configuration and restart the cluster
                 Key: STORM-2773
                 URL: https://issues.apache.org/jira/browse/STORM-2773
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-client
    Affects Versions: 2.0.0
            Reporter: liuzhaokun
            Assignee: liuzhaokun


There is a cluster which includes three nodes named storm1,storm2,storm3.And there is a drpcserver in every node,a worker which has been started on strom1.When strom1 was down with hardware failure,my drpc topology won't work,when I send request from drpcclient.
As storm1 was down,so the worker will be restarted on another node,but it can't Initialize successfully because the call method of Adder will throw a RuntimeException,when drpcspout try to connect to storm1,so the worker will restart again. 

In conclusion,If a drpcserver node in cluster is down,drpc cluster won't work until we modify the drpc.server configuration and restart the cluster,but in production,it's difficult to restart whole cluster.

So I think we should catch the RuntimeException and log it,and the drpc topology will work normally.
