Can you look at the new patch, [~brandon.williams]?

>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Hadoop
>            Reporter: Victor Igumnov
>            Priority: Minor
>             Fix For: 2.1 rc1

> See Github for patch:
> What the patch does:
> While I was evaluating Shark/Hive for analyzing Cassandra's data, I could not get any
of the queries to return reliably. Looking further into the issue I noticed that if just a
single fetch for a split fails the whole job is aborted. So instead of giving up and failing
out the whole job, retry fetching the data a few times before completely giving up.
