> Project: Apache Storm
> Issue Type: Bug
> Components: storm-client
> Affects Versions: 2.0.0

> 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.
