>    Affects Versions: 2.0.0

>
> Currently split flow is such that we close the parent region and all its 
> store file readers are also closed.  After that inorder to split the 
> reference files we need the first and last keys for which once again open the 
> readers on those store files.  This could be costlier operation considering 
> the fact that it has to contact the HDFS for this close and open operation. 
> This JIRA is to see if we can improve this.
