Ethan Li commented on STORM-2983:
---------------------------------
I think [~kabhwan] has a very good point. So I am proposing:
1) a new Jira for RAS issues.
We all agree that RAS issues are important and need to be addressed. I
believe it's better to have a separate Jira to discuss and fix them in the
right way.
2) checking whether outgoing stream/tasks/connections exists in the worker
instead of checking topology.worker. I agree that this is the right way to do
it and it's more flexible. It also keeps this minor optimization.
> Some topologies not working properly

> Key: STORM-2983
> URL: https://issues.apache.org/jira/browse/STORM-2983
> Project: Apache Storm
> Issue Type: Bug
> Reporter: Ethan Li
> Assignee: Ethan Li
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> For example,
> {code:java}
> bin/storm jar storm-loadgen-*.jar
> org.apache.storm.loadgen.ThroughputVsLatency --spouts 1 --splitters 2
> --counters 1 -c topology.debug=true
> {code}
> on ResourceAwareScheduler not working properly.
> With default cluster settings, there will be only one __acker-executor and it
> will be on a separate worker. And it looks like the __acker-executor was not
> able to receive messages from spouts and bolts. And spouts and bolts
> continued to retry sending messages to acker. It then led to another problem:
> STORM-2970
> I tried to run on storm right before
> [https://github.com/apache/storm/pull/2502] and right after and confirmed
> that this bug should be related to it
