---------------------------------
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.
