> Project: Cassandra
> Issue Type: Improvement
> Components: Hadoop
> Reporter: Victor Igumnov
> Priority: Minor
> Fix For: 2.1.1

> 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.
