> Formalize the AppMaster environment for docker compability
> ----------------------------------------------------------
>
> Key: FLINK-5091
> URL: https://issues.apache.org/jira/browse/FLINK-5091
> Project: Flink
> Issue Type: Sub-task
> Components: Cluster Management, Mesos
> Reporter: Eron Wright
> Assignee: Eron Wright
> Fix For: 1.2.0
>
>
> For scenarios where the AppMaster is launched from a docker image, it would
> be ideal to use the installed Flink rather than rely on a special file layout
> in the sandbox directory.
> This is related to DCOS integration, which (in 1.2) will launch the AppMaster
> via Marathon (as a top-level DCOS service). The existing code assumed that
> only the dispatcher (coming in 1.3) would launch the AppMaster.
