Andrew Kyle Purtell resolved HBASE-10983.
-----------------------------------------
Resolution: Won't Fix
> Enhance LoadIncrementalHFile with option to do splitting in a distributed
> fashon
> --------------------------------------------------------------------------------
>
> Key: HBASE-10983
> URL: https://issues.apache.org/jira/browse/HBASE-10983
> Project: HBase
> Issue Type: Improvement
> Reporter: Theodore michael Malaska
> Priority: Minor
>
> Currently LoadIncrementalHFile supports splitting HFiles if they don't match
> up with the current regions of the table being imported too.
> However this functionality of reading and rewriting the HFile is done through
> a single JVM, which limits the overall speed of the splitting process.
> This jira will allow the user to set a flag or a threshold (on the total size
> of the HFiles to be split) that may trigger the splitting logic to be
> executed through a Map Only job as opposed to the existing thread pool in a
> single JVM.
> I will have the following goals when writing this patch:
> 1. Extend LoadIncrementalHFile
> 2. Reuse as much code from LoadIncrementalHFile as possible
