> PROBLEM: The deployed kafkaspout showed "failures" in the Storm UI, however
> there were no exceptions. The latency was high. Currently,
> topology.max.spout.pending is set to null via ambari and if the topology does
> not override it, it will not be set.
> At this point this can be set for kafkaspout configuration object in the
> topology code.
