      Description

      There is a bug in HBaseFsck's adoptHdfsOrphan function.At the last of this function will create a region,which want to cover all the orphan regions.But the end key of this new region was set incorrectly.Correct region's boundary should be [startKey,endKey),but this function create a region with boundary of [startKey,endKey],this bug will leads to scan operation omit some data.
      I think we should create the region like bellow,
      // create new region on hdfs. move data into place.
      HRegionInfo hri = new HRegionInfo(template.getTableName(), orphanRegionRange.getFirst(),
      Bytes.add(orphanRegionRange.getSecond(), new byte[1]));
