jschmidt10 opened a new issue, #3348:
URL: https://github.com/apache/accumulo/issues/3348
**Describe the bug**
The SplitUtils.getRangeLength() method can return a negative number (due to
overflow) for certain Ranges. This became a problem for us using Spark 3.2.x
where the default behavior is to ignore empty splits - they actually drop
InputSplits where getLength() returns < 0.
**To Reproduce**
Here's a sample range:
```
Key begin = new Key("aaaaaaa");
Key end = new Key(new byte[] {
(byte) 0xFF,
(byte) 0xFF,
(byte) 0xFF,
(byte) 0xFF,
(byte) 0xFF,
(byte) 0xFF,
(byte) 0xFF
});
Range range = new Range(begin, end);
System.out.println(SplitUtils.getRangeLength(range));
```
That will print out an overflowed Long that has been flipped to a massively
negative number.
**Expected behavior**
This should return a number > 0.
