>                 Key: HBASE-3879
>                 URL: https://issues.apache.org/jira/browse/HBASE-3879
>             Project: HBase
>          Issue Type: Improvement
>          Components: regionserver
>            Reporter: Ophir Cohen
>            Priority: Minor
>
> Currently the split point picked to be the mid key of the HFile. 
> From the code comments: 
> "Midkey for this file.  We work with block boundaries only so
>      * returned midkey is an approximation only."
> It could be good to have a way to override the default option and use other method.
> Possible implementation:
> Create interface (similar to Hadoop's partitioner) that gets StoreFile / StoreFile.Reader and return the splitting point.
