Marcelo Vanzin commented on SPARK-23103:
----------------------------------------
Given the unit test failure in the PR it might not be as minor; but I haven't
looked at that yet (looking at another bug still).
> LevelDB store not iterating correctly when indexed value has negative value

> Key: SPARK-23103
> URL: https://issues.apache.org/jira/browse/SPARK-23103
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Marcelo Vanzin
> Priority: Minor
>
> 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:
>
> {noformat}
> [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
> {noformat}
