-----------------------------------------
Thanks for the review [~anishek]!
Test failures are irrelevant to the patch and it is committed to master!

> Project: Hive
> Issue Type: Sub-task
> Components: Transactions
> Affects Versions: 3.0.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Priority: Major
> Labels: ACID, UDF, pull-request-available
> Fix For: 3.0.0

> Attachments: HIVE-18751.01.patch
>
>
> Per table write ID (HIVE-18192) have replaced global transaction ID with
> write ID to version data files in ACID/MM tables,
> To ensure snapshot isolation, need to generate ValidWriteIdList for the given
> txn/table and use it when scan the ACID/MM tables.
> In case of get_splits UDF which runs on ACID table scan query won't receive
> it properly through configuration (hive.txn.tables.valid.writeids) and hence
> throws exception.
> TestAcidOnTez.testGetSplitsLocks is the test failing for the same. Need to
> fix it.
