Subject Big + small + small 3 table mapjoin?
Date Tue, 08 Mar 2016 17:31:01 GMT
>From the documentation it says that if my tables are small enough and i set
the conver join parameters, without the join hints hive should be able to
convert the joins into 1 mapjoin in 1 mr job

But in practice i found that it always ends up in 2 mr jobs (2 map joins).
What is wrong?
