Subject RE: Why is the toplogy.workers is hardcoded to 1
Date Thu, 26 Feb 2015 20:40:17 GMT
Thanks for the reply Harsha. We have distributed supervisor nodes (2) and a nimbus node. The
storm.yaml file has topology.workers property commented out. When a topology gets submitted
that has one spout and a bolt with parallelism hint of 10 for each, before 0.9.3 upgrade storm
distributes  this work across multiple worker process. The supervisor slots configured in
the three nodes has a value 6701, 6702, 6703.

When such topology is submitted in storm now(after the upgrade), it’s just one worker process
that gets created with 21 executor threads. Shouldn’t storm distribute the work?

Srividhya,
        Storm topologies requires at least one worker to be available to run. Hence the config
will set as 1 for the topology.workers as default value. Can you explain in more detail what
you are trying to achieve.
Thanks,
Harsha

I have commented this property in the storm.yaml. But still it always defaults to 1 after
we upgraded storm to 0.9.3. Any idea why its hardcoded?
