--------------------------------------------
Summary: Bucket map join requires exact number of files as number
of buckets
Key: HIVE-11845
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.
