[jira] [Updated] (TINKERPOP-1525) Plug VertexProgram iteration leak
on empty Spark RDD partitions
[ https://issues.apache.org/jira/browse/TINKERPOP-1525?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stephen mallette updated TINKERPOP-1525:
----------------------------------------
Affects Version/s: (was: 3.3.0)
Component/s: hadoop
> Plug VertexProgram iteration leak on empty Spark RDD partitions
> ---------------------------------------------------------------
>
> 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
>
> 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.
