manolama opened a new issue, #38366:
URL: https://github.com/apache/arrow/issues/38366
### Describe the bug, including details regarding any error messages,
version, and platform.
When attempting to use the `MurmurHasher` for values like `foo` and `bar`,
the same hash was produced.
Reproduction:
```
@Test
public void testHasherLessThanInt() {
try (ArrowBuf buf1 = allocator.buffer(4);
ArrowBuf buf2 = allocator.buffer(4)) {
buf1.writeBytes("foo1".getBytes(StandardCharsets.UTF_8));
buf2.writeBytes("bar2".getBytes(StandardCharsets.UTF_8));
for (int i = 1; i <= 4; i ++) {
verifyHashCodeNotEqual(buf1, 0, i, buf2, 0, i);
}
}
}
private void verifyHashCodeNotEqual(ArrowBuf buf1, int offset1, int
length1,
ArrowBuf buf2, int offset2, int
length2) {
int hashCode1 = hasher.hashCode(buf1, 0, length1);
int hashCode2 = hasher.hashCode(buf2, 0, length2);
System.out.println(hashCode1 + " != " + hashCode2);
//assertNotEquals(hashCode1, hashCode2);
}
```
produces
```
-1684229222 != -1684229222
-26109336 != -26109336
-235476567 != -235476567
779730367 != 296486961
```
