Review comment:
`First check if we have Hadoop in the ClassPath.` -> `First check if we have
Hadoop specific dependencies in the ClassPath.` looks better to me

> Support Hadoop-free variant of Flink on Mesos
> ---------------------------------------------
>
> Key: FLINK-8247
> URL: https://issues.apache.org/jira/browse/FLINK-8247
> Project: Flink
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 1.4.0
> Reporter: Eron Wright
> Assignee: Eron Wright
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.4.3, 1.5.4
>
>
> In Hadoop-free mode, Hadoop isn't on the classpath. The Mesos job manager
> normally uses the Hadoop UserGroupInformation class to overlay a user context
> (`HADOOP_USER_NAME`) for the task managers.
> Detect the absence of Hadoop and skip over the `HadoopUserOverlay`, similar
> to the logic in `HadoopModuleFactory`. This may require the introduction
> of an overlay factory.
