Maximilian Michels commented on FLINK-2823:
-------------------------------------------
I will open a new pull request to address this issue. I would like to only
throw an exception if 1) no Hadoop environment variables are set AND 2) no
Hadoop configuration is present in the classpath.
> 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: 0.10.0
> Reporter: Stephan Ewen
> Assignee: Maximilian Michels
> Fix For: 1.0.0
>
>
> 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.
