Hi [~tejasp] [~chengsu]

How to join two bucketed tables, when tables are bucketed on multiple columns. I tried to join, but still exchanges were getting created.

Below is the scenario:

table1 bucketed by a 10 buckets

table2 bucketed by a,b 10 bucktes

how to join table1 and table2 on column a without exchanges?
