-------------------------------------
I means maybe hbck did two steps to fix orphan regions. First create new region
cover all orphan HFiles. Second,just fix meta data which not refers to any
actual physical data if there still are holes in region chain. For example, the
hole [cx\00,d) will be fixed by the next step operation fix meta.
> HBaseFsck's adoptHdfsOrphan function creates region with wrong end key
> boundary

> 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]));
