      Description

      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.
