["Ted Yu (JIRA)" <ji...@apache.org>]

Ted Yu created HBASE-15772:
------------------------------

             Summary: Switch to the new RegionObserver#preStoreScannerOpen() method which accepts read point parameter
                 Key: HBASE-15772
                 URL: https://issues.apache.org/jira/browse/HBASE-15772
             Project: HBase
          Issue Type: Task
            Reporter: Ted Yu


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