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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
