> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 1.2.1
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
>
> create table acidTblPart (a int, b int) partitioned by (p string) clustered
> by (a) into " + BUCKET_COUNT + " buckets stored as orc TBLPROPERTIES
> ('transactional'='true')
> update acidTblPart set b = 17 where p = 1
> This acquires share_write on the table while based on p = 1 we should be able
> to figure out that only 1 partition is affected and only lock the partition
> Same should apply to DELETE
