Robert Metzger commented on FLINK-2823:
---------------------------------------
I think {{HADOOP_HOME}} is deprecated with the Hadoop 2 releases.
The problem is that users are not reading the log output, because it actually
logs WARNing messages in case the environment variables are not set or when the
file system is set to a local FS.
> 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.
