Sahil Takiar commented on HIVE-18054:
-------------------------------------
Can you create an RB?
Some comments:
* Executing multiple queries in parallel seems flaky. If this feature is
broken, then the test would only fail intermittently
* Other than that it mostly looks like refactoring, are there any other classes
(besides MoveWork, QueryState, SessionState, LineageState that are modified)
> Make Lineage work with concurrent queries on a Session

> 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.
