Rick Kellogg updated STORM-836:
-------------------------------
Component/s: storm-core
> DPRC request failed after DRPC server restarted
> -----------------------------------------------
>
> Key: STORM-836
> URL: https://issues.apache.org/jira/browse/STORM-836
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 0.9.3
> Reporter: Yohn Wei
> Assignee: Yohn Wei
>
> When the DRPC server was killed and then restarted, the DRPC client would
> throw a DRPCExecutionException (msg:Request failed) for a while, off and on.
> Here is my client code:
> {code:java}
> DRPCClient client = new DRPCClient("hd181", 3772);
> for (int i = 0; i < 100; ++i) {
> System.out.println(client.execute("drpcFunc", "aaa"));
> }
> {code}
> and the error messages:
> {code}
> Exclamation-6:aaa!!!
> Exception in thread "main" DRPCExecutionException(msg:Request failed)
> at
> backtype.storm.generated.DistributedRPC$execute_result.read(DistributedRPC.java:904)
> at org.apache.thrift7.TServiceClient.receiveBase(TServiceClient.java:78)
> at
> backtype.storm.generated.DistributedRPC$Client.recv_execute(DistributedRPC.java:92)
> at
> backtype.storm.generated.DistributedRPC$Client.execute(DistributedRPC.java:78)
> at backtype.storm.utils.DRPCClient.execute(DRPCClient.java:71)
> at com.enjoyor.storm.kafka.example.DRPCTest.main(DRPCTest.java:18)
> {code}
> As you can see, the client can get few valid results at beginning and then
> get a failed request.
> This problem would last about 10 minutes after restarting the server, and
> then the server would be back to normal.
