>
> 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.
