Hi , I have a small doubt in how hive handles queries containing join of more than 2 tables .
Suppose we have 3 tables A,B,C .. and the plan is "((AB)C)" .. We can join A,B in a map reduce job and join the resultant table with "C". I have a doubt whether the result of "AB" is stored to disk before joining with C or is it streamed directly to join with C (I don't know how , just a guess) . Any help is appreciated , Thanks
