Namit Jain commented on HIVE-3260:
----------------------------------
I agree - this code is not the difficult part.
But, we need to make sure everywhere partition metadata is getting used, like
in sampling etc.
Let us defer it for now, and get back to it later.
Do you want to open the jira for now ?
> support bucketed mapjoin where the small table has different number of
> buckets for different partitons

> Consider the following scenario:
> A (1 partition) join B (2 partitions)
> A has 2 buckets, whereas B has 2 and 4 buckets for different partitions.
> The bucketed mapjoin should still work.
