Jungtaek Lim commented on STORM-2983:
-------------------------------------
If we really want to address this via not removing micro optimization but
fixing it, it can be done in the right way. It would be better to check whether
there're outgoing tasks/connections in each worker, not just checking topology
worker count.
> 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
