---------------------------------------
Github user mxm commented on the issue:
https://github.com/apache/flink/pull/2187
I moved one existing environment variable `FLINK_CONF_DIR` to
`ConfigConstants`. I added the `FLINK_LIB_DIR` environment variable to load a
library folder (optional). I'm not sure whether we should add them to the
documentation since they are set by the bash scripts and shouldn't be exposed
to the user.
> YARN ship folder incosistent behavior
> -------------------------------------
>
> Key: FLINK-3675
> URL: https://issues.apache.org/jira/browse/FLINK-3675
> Project: Flink
> Issue Type: Bug
> Components: YARN Client
> Affects Versions: 1.0.0
> Reporter: Stefano Baghino
> Assignee: Maximilian Michels
> Priority: Critical
> Fix For: 1.1.0
>
>
> After [some discussion on the user mailing
> list|http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Flink-and-YARN-ship-folder-td5458.html]
> it came up that the {{flink/lib}} folder is always supposed to be shipped to
> the YARN cluster so that all the nodes have access to its contents.
> Currently however, the Flink long-running YARN session actually ships the
> folder because it's explicitly specified in the {{yarn-session.sh}} script,
> while running a single job on YARN does not automatically ship it.
