---------------------------------------
Assignee: Zoltan Haindrich
> Hive lineage is not generated for insert overwrite queries on partitioned
> tables
> --------------------------------------------------------------------------------
>
> Key: HIVE-22301
> URL: https://issues.apache.org/jira/browse/HIVE-22301
> Project: Hive
> Issue Type: Bug
> Components: lineage
> Affects Versions: 3.1.2
> Reporter: Sidharth Kumar Mishra
> Assignee: Zoltan Haindrich
> Priority: Major
> Attachments: ScreenShot HookContext.png, ScreenShot
> RunPostExecHook.png, ScreenShot runBeforeExecution.png

>
> Problem: When I run the below mentioned queries, the last query should have
> given the proper hive lineage info (through HookContext) from table_b to
> table_t.
> * Create table table_t (id int) partitioned by (dob date);
> * Create table table_b (id int) partitioned by (dob date);
> * from table_b a insert overwrite table table_t select a.id,a.dob;
> Note : for CTAS query from a partitioned table , this issue is not seen. Only
> for insert queries like insert into <table> select * from <table> and query
> like above, issue is seen.
>
> Technical Observations:
> At HookContext (passed from hive.ql.Driver to Hive Hook of Atlas through
> hookRunner.runPostExecHooks call) contains no outputs. Check below screenshot
> from IntelliJ.
> !ScreenShot RunPostExecHook.png|width=728,height=427!
>
> I found that the PrivateHookContext is getting created with proper outputs
> value as shown below initially:
> !ScreenShot HookContext.png|width=714,height=541!
> The same is passed properly to runBeforeExecutionHook as shown below:
> !ScreenShot runBeforeExecution.png|width=719,height=620!
>
> Later when we pass HookContext to runPostExecHooks, there is no output
> populated. Kindly check the reason and let me know if you need any further
> information from my end.
