Navis commented on HIVE-3260:
-----------------------------
It is right thing which should be done.
But why not support buckets per partition? Would it be enough to change the
code above to
{code}
int bucketNum = sd.getNumBuckets();
return bucketNum < 0 ? table.getNumBuckets() : bucketNum;
{code}
and add some DDL syntax for partition?
> 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.
