Description

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.
