caofangkun created HIVE-9589:
--------------------------------

             Summary: config topology.acker.executors default value should not be null
                 Key: HIVE-9589
                 URL: https://issues.apache.org/jira/browse/HIVE-9589
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.10.0
            Reporter: caofangkun
            Assignee: caofangkun
            Priority: Minor


See Code:
https://github.com/caofangkun/apache-storm/blob/master/storm-core/src/clj/backtype/storm/daemon/common.clj#L315

Config "topology.acker.executors" default value is null
then acker executors will be same as "topology.workers"

$ storm jar storm-starter-0.10.0-SNAPSHOT.jar storm.starter.ExclamationTopology ExclamationTopology

Executors show up as 18 executors = 10(word) + 3(exclaim1) + 2(exclaim2) + 3(acker bolt) 

But the 3 acker bolt executors will not be used.
