[jira] [Created] (HIVE-18054) Make Lineage work with concurrent queries on a Session

Andrew Sherman created HIVE-18054:
-------------------------------------

             Summary:  Make Lineage work with concurrent queries on a Session
                 Key: HIVE-18054
                 URL: https://issues.apache.org/jira/browse/HIVE-18054
             Project: Hive
          Issue Type: Bug
            Reporter: Andrew Sherman
            Assignee: Andrew Sherman


A Hive Session can contain multiple concurrent sql Operations.
Lineage is currently tracked in SessionState and is cleared when a query completes. This results in Lineage for other running queries being lost.
To fix this, move LineageState from SessionState to QueryState.
