Anton Nazaruk updated HBASE-14206:
----------------------------------
    Description: 
I haven't found a way to attach test program to JIRA issue, so put it below :

{code}
public class MultiRowRangeFilterTest {
 
    byte[] key1Start =    new byte[] {-3};
    byte[] key1End =    new byte[] {-2};

    byte[] key2Start =    new byte[] {5};
    byte[] key2End =    new byte[] {6};

    byte[] badKey = new byte[] {-10};

    @Test
    public void testRanges() throws IOException {
        MultiRowRangeFilter filter = new MultiRowRangeFilter(Arrays.asList(
                new MultiRowRangeFilter.RowRange(key1Start, true, key1End, 
false),
                new MultiRowRangeFilter.RowRange(key2Start, true, key2End, 
false)
        ));
        filter.filterRowKey(badKey, 0, 1);
        /*
        * FAILS -- includes BAD key!
        * Expected :SEEK_NEXT_USING_HINT
        * Actual   :INCLUDE
        * */
        assertEquals(Filter.ReturnCode.SEEK_NEXT_USING_HINT, 
filter.filterKeyValue(null));
    }
}
{code}

It seems to happen on 2.0.0-SNAPSHOT too, but I wasn't able to link one with 
included class.

I have played some time with algorithm, and found that quick fix may be applied 
to "getNextRangeIndex(byte[] rowKey)" method (hbase-client:1.1.0) :

{code}
if (insertionPosition == 0 && 
!rangeList.get(insertionPosition).contains(rowKey)) {
        return ROW_BEFORE_FIRST_RANGE;
}
// FIX START
if(!this.initialized) {
    this.initialized = true;
}
// FIX END
return insertionPosition;
{code} 

Thanks, hope it will help.
