> Fix KeyOnlyFilter + Add Value Length
> ------------------------------------

> Key: HBASE-3232
> URL: https://issues.apache.org/jira/browse/HBASE-3232
> Project: HBase
> Issue Type: Bug
> Reporter: Nicolas Spiegelberg

> Priority: Blocker
> Fix For: 0.90.0

>
> HBASE-3211 altered filter code to mutate KeyValues. What could go wrong?
> Well, your scan could mess up because the KVHeap compare functions don't work
> properly. If we're going to soft mutate KVs in filter code, we also need to
> soft copy the KV before filtering. This was found while adding the ability
> to have KeyOnlyFilter have the option to return the Value's length. This is
> useful for grouping your reduce tasks into equal-sized blocks.
