> URL: https://issues.apache.org/jira/browse/HIVE-11845
> Project: Hive
> Issue Type: Bug
> Affects Versions: 1.3.0, 2.0.0
> Reporter: Prasanth Jayachandran
> Assignee: Vikram Dixit K
>
> I recently tried to write a test case for bucket map join in tez on ACID
> table but was unable to do so because bucket map join expects same number of
> files in table/partition as that of number of buckets.
> Steps to reproduce:
> create table src_acid(key string, value string) clustered by (key) into 4
> buckets stored as orc tblproperties("transactional"="true");
> insert into table src_acid values("key1","value1");
> insert into table src_acid values("key2","value2");
> After inserting 2 rows into the src_acid table, there will be total of 8
> files in the table directory which does not match the number of buckets.
