> KeyValue kv1 = new KeyValue(Bytes.toBytes("aaa"), Bytes.toBytes("fam1"),
> Bytes.toBytes("q1"),
> Bytes.toBytes("val"));
> writer.append(kv1);
> KeyValue kv2 = new KeyValue(Bytes.toBytes("aab"), Bytes.toBytes("fam1"),
> Bytes.toBytes("q1"),
> Bytes.toBytes("val"));
> writer.append(kv2);
> KeyValue kv4 = new KeyValue(Bytes.toBytes("aac"), Bytes.toBytes("fam1"),
> Bytes.toBytes("q1"),
> Bytes.toBytes("val"));
> writer.append(kv4);
> KeyValue kv5 = new KeyValue(Bytes.toBytes("aac"), Bytes.toBytes("fam12"),
> Bytes.toBytes("q2"),
> Bytes.toBytes("val"));
> writer.append(kv5);
> {code}
> {code}
> KeyValue toSeek = new KeyValue(Bytes.toBytes("aac"),
> Bytes.toBytes("fam1"),
> Bytes.toBytes("q2"), Bytes.toBytes("val"));
> StoreFileScanner s = reader.getStoreFileScanner(false, false);
> s.reseek(toSeek);
> {code}
> Now calling s.next() should point to the last KV - kv5.
> Before calling s.next() it would have done a moveToPrevious since there is no
> KV that exactly matches with the toSeek key.
> Incase of NONE, PREFIX, DIFF, FAST_DIFF things work fine as expected.
> But in case of Prefix Tree, calling reseek() points to a key that is same as
> the toSeek key which does not exist at all.
> Will attach a testcase that shows this problem.
