>             Project: Flink
>          Issue Type: Bug
>          Components: YARN Client
>    Affects Versions: 0.10

>             Fix For: 0.10

> The important variables are {{HADOOP_HOME}} and {{HADOOP_CONF_DIR}}.
> If none of the two environment variables are set, the YARN client does not pick the correct
settings / file system to successfully deploy a job.
> The YARN client should throw a good exception. Right now, this requires some tricky debugging
to find the cause of the problem.
