Description

Marking as minor since I don't believe we currently have anything that needs to store negative values in indexed fields. But I wrote a unit test and got:

 

[error] Test org.apache.spark.util.kvstore.LevelDBSuite.testNegativeIndexValues failed: java.lang.AssertionError: expected:<[-50, 0, 50]> but was:<[[0, -50, 50]]>, took 0.025 sec
