Alex Liu commented on CASSANDRA-6091:
-------------------------------------

We need at least check the total estimated rows of multiple token ranges per split, instead
of multiple taken ranges per node.

> Better Vnode support in hadoop/pig

> CASSANDRA-6084 shows there are some issues during running hadoop/pig job if vnodes are
enable. Also the hadoop performance of vnode enabled nodes  are bad for there are so many
splits.
> The idea is to combine vnode splits into a big sudo splits so it work like vnode is disable
for hadoop/pig job
