> 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,
> {code}
>     // create new region on hdfs. move data into place.
>     HRegionInfo hri = new HRegionInfo(template.getTableName(), orphanRegionRange.getFirst(),
>         Bytes.add(orphanRegionRange.getSecond(), new byte[1]));
> {code}
> This is to backport to branch-1.1 and branch-1.2
