> DO NOT purge the output location if it has content in SparkGraphComputer
> ------------------------------------------------------------------------
>
> Key: TINKERPOP-2941
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2941
> Project: TinkerPop
> Issue Type: Improvement
> Affects Versions: 3.6.2
> Reporter: Redriver
> Priority: Major
>
> The default logic for SparkGraphComputer is to purge all content if the
> output location is specified. That is a dangerous operation especially for
> the output location which contains contents.
> https://github.com/apache/tinkerpop/blob/master/spark-gremlin/src/main/java/org/apache/tinkerpop/gremlin/spark/process/computer/SparkGraphComputer.java#L317:L324
> The correct behavior is to stop the process if it detects the output location
> is not empty.
