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]));
