anishek created HIVE-16893:
------------------------------

             Summary: move replication related work in semantic analysis phase to execution phase using a task
                 Key: HIVE-16893
                 URL: https://issues.apache.org/jira/browse/HIVE-16893
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: anishek
            Assignee: anishek
             Fix For: 3.0.0


Since we run in to the possibility of creating a large number tasks during replication bootstrap dump
* we may not be able to hold all of them in memory for really large databases, which might not hold true once we complete HIVE-16892
* Also a compile time lock is taken such that only one query is run in this phase which in replication bootstrap scenario is going to be a very long running task and hence moving it to execution phase will limit the lock period in compile phase.
