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

             Summary: Backport HBASE-15125 'HBaseFsck's adoptHdfsOrphan function creates region
with wrong end key boundary' to Apache HBase 1.1
                 Key: HBASE-15852
                 URL: https://issues.apache.org/jira/browse/HBASE-15852
             Project: HBase
          Issue Type: Bug
          Components: hbck
    Affects Versions: 1.1.5
            Reporter: Stephen Yuan Jiang
            Assignee: Stephen Yuan Jiang


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 HBASE-15125 to branch-1.1.  HBASE-15827 could not do it due to a bug in
TestHBaseFsck test suite (see HBASE-15850)
