Victor Igumnov commented on CASSANDRA-7106:
-------------------------------------------
Fixed an issue with my last patch, I should have made a copy of the key set to
avoid a concurrent modification exception when modifying the collection.
retries-fix-iterator-bug.patch should be the patch that is reviewed.

> Key: CASSANDRA-7106
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7106
> Project: Cassandra
> Issue Type: Improvement
> Components: Hadoop
> Reporter: Victor Igumnov
> Priority: Minor
> Fix For: 2.1 beta1
>
> Attachments: retries-fix-iterator-bug.patch, retries-reworked.patch,
> retry-splits.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.
