---------------------------------

             Summary: Divide by zero error in HybridHashTableContainer
                 Key: HIVE-10606
                 URL: https://issues.apache.org/jira/browse/HIVE-10606
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Jason Dere
            Assignee: Jason Dere


Looks like this occurs when hive.auto.convert.join.noconditionaltask.size is set to a value lower than hive.exec.reducers.max. This is a very unlikely scenario (hit this while trying to test some stuff out in local mode), but this shouldn't happen.
