URL: https://github.com/apache/tinkerpop/pull/2053
In production environment, it is dangerous to delete a folder which is not
empty. In order to avoid any wrong operations, it is better ask user to delete
it manually if it is not empty.
> DO NOT purge the output location if it has content in SparkGraphComputer

> 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.

> The correct behavior is to stop the process if it detects the output location
> is not empty.
