[jira] [Created] (HBASE-14206) MultiRowRangeFilter returns records
whose rowKeys are out of allowed ranges
Anton Nazaruk created HBASE-14206:
-------------------------------------
Summary: MultiRowRangeFilter returns records whose rowKeys are out of allowed ranges
Key: HBASE-14206
URL: https://issues.apache.org/jira/browse/HBASE-14206
Project: HBase
Issue Type: Bug
Affects Versions: 1.1.0
Environment: linux, java7
Reporter: Anton Nazaruk
Assignee: Ted Yu
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.
