>                 Key: TINKERPOP-1525
>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1525
>             Project: TinkerPop
>          Issue Type: Bug
>          Components: hadoop
>    Affects Versions: 3.2.3
>            Reporter: Dan LaRocque
>             Fix For: 3.2.4
>
>
> If SparkExecutor gets an RDD with empty partitions, it can invoke {{VertexProgram.workerIterationStart}} without ever invoking {{VertexProgram.workerIterationEnd}}.
> For vertex programs that allocate and release meaningful resources in the start/end methods, this can lead to resource leaks.
> I already tested a fix that I made against the 3.2 series.  I will submit PRs momentarily.
