Throws:

IOException

testPreadReversedScan01

public void testPreadReversedScan01()
                             throws IOException

all rowKeys are fit in the last region.

Throws:

IOException

testPreadReversedScanInternal

private void testPreadReversedScanInternal(String[] inputRowKeys)
                                    throws IOException

Throws:

IOException

testSmallReversedScan02

public void testSmallReversedScan02()
                             throws IOException

Corner case:

HBase has 4 regions, (-oo,b),[b,c),[c,d),[d,+oo), and only rowKey with byte[]={0x00} locate in region (-oo,b) . test whether reversed pread scanner will return infinity results with RowKey={0x00}.

Throws:

IOException
