Subject [jira] [Commented] (CASSANDRA-6091) Better Vnode support in hadoop/pig
Date Wed, 11 Feb 2015 23:44:13 GMT

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

One more improvement is combining adjacent token ranges into one range. But it will create
some small corner ranges, so the trade off is not that good as "as the number of adjacent
token ranges is going to drop very quickly with the size of the cluster.

> 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
