-----------------------------------

             Summary: YARN client should report a proper exception if Hadoop Env variables are not set
                 Key: FLINK-2823
                 URL: https://issues.apache.org/jira/browse/FLINK-2823
             Project: Flink
          Issue Type: Bug
          Components: YARN Client
    Affects Versions: 0.10
            Reporter: Stephan Ewen
             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.
