Dmytro Sen created AMBARI-12815:
-----------------------------------

             Summary: Change the default of topology.max.spout.pending from null to 1000 for Storm to prevent failures for Spout
                 Key: AMBARI-12815
                 URL: https://issues.apache.org/jira/browse/AMBARI-12815
             Project: Ambari
          Issue Type: Bug
          Components: stacks
    Affects Versions: 2.0.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
            Priority: Critical
             Fix For: 2.1.2


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.
