----------------------------------------------

             Summary: Avoid Splits to create a closed reader for fetching the first and last
key
                 Key: HBASE-14643
                 URL: https://issues.apache.org/jira/browse/HBASE-14643
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 2.0.0
            Reporter: ramkrishna.s.vasudevan


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.
