-----------------------------------------
I assume that you are referring to STORM-292. I will raise a separate PR for
that one. Have assigned that issue to myself.
> Topology may hang because metric-tick function is a blocking call from spout

> Key: STORM-1027

> Project: Apache Storm
> Issue Type: Bug
> Affects Versions: 0.10.0
> Reporter: Abhishek Agarwal
> Priority: Critical

> Nathan had fixed the dining philosopher problem by putting a overflow buffer
> in the spout so that spout is not blocking. However, overflow buffer is not
> used when emitting the metric, and that could result in the deadlock. I
> modified the executor to use overflow buffer for emitting metrics and
> afterwards topology didn't hang.
