Description

Over in HBASE-15759, the following method is added to RegionObserver :

  public KeyValueScanner preStoreScannerOpen(final ObserverContext<RegionCoprocessorEnvironment> c,
      final Store store, final Scan scan, final NavigableSet<byte[]> targetCols,
      final KeyValueScanner s, final long readPt) throws IOException {

Currently the preStoreScannerOpen() without read point parameter is used in IndexHalfStoreFileReaderGenerator

We need to switch over to calling the new method for hbase 2.0
