Hi, I am trying to use uniquejoin to join multiple tables with same key in one mapreduce job. It works well if I stage individual partition data in temporary staging tables. But, if I make it work on top of partitioned tables, I do not get any output. Does anyone know how to fix this?
I am using following syntax- INSERT INTO ... SELECT ..... FROM UNIQUEJOIN PRESERVE table1 (keys...) PRESERVE table2 (keys...) WHERE t1.partitionkey = X and t2.partitionkey = X It works well, if I copy table1 table2's partitions into table1_stage, table2_stage which are unpartitioned tables. Thanks, Aniket
