Alex Liu commented on CASSANDRA-6091:
-------------------------------------
If two token ranges have the same list of endpoints, they can be merged into a
sudo token range. e.g.
{code}
Range A [start_a, end_a) has endpoints[node_1, node_5, node_8]
Range B [start_b, end_c) has endpoints[node_1, node_5, node_8]
can be merged to
sudo token range Sudo_Range_A_B [[start_a, end_a), [start_b, end_b)]
{code}
We need modify CqlPagingRecordRead to support multiple token ranges split
> 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
