             Summary: Execution framework in hive to run tasks in parallel 
other than MR Tasks
                 Key: HIVE-17426
                 URL: https://issues.apache.org/jira/browse/HIVE-17426
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: anishek
            Assignee: anishek
             Fix For: 3.0.0


the execution framework currently only runs MR Tasks in parallel when {{set 
hive.exec.parallel=true}}.

Allow other types of tasks to run in parallel as well to support replication 
scenarios in hive. TezTask / SparkTask will still not be allowed to run in 
parallel.
