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

             Summary: NPE in StoreFileScanner during reverse scan
                 Key: HBASE-15884
                 URL: https://issues.apache.org/jira/browse/HBASE-15884
             Project: HBase
          Issue Type: Bug
          Components: Scanners
    Affects Versions: 2.0.0
            Reporter: Sergey Soldatov


Here is a part of {{skipKVsNewerThanReadpoint}} method:
{noformat}
      hfs.next();
      setCurrentCell(hfs.getKeyValue());
      if (this.stopSkippingKVsIfNextRow
          && getComparator().compareRows(cur.getRowArray(), cur.getRowOffset(),
              cur.getRowLength(), startKV.getRowArray(), startKV.getRowOffset(),
              startKV.getRowLength()) > 0) {

{noformat}
If hfs has no more KVs, cur will be set to Null and on on the next step will throw NPE.
