+## Configuring Flink with Hadoop Classpaths
+
+Flink will use the environment variable `HADOOP_CLASSPATH` to augment the
+classpath that is used when starting Flink components such as the Client,
+JobManager, or TaskManager. Most Hadoop distributions and cloud
environments
+will not set this variable by default so if the Hadoop classpath should be
+picked up by Flink the environment variable must be exported on all
machines
+that are running Flink components.
+
+When running on YARN, this is usually not a problem because the components
+running inside YARN will be started with the Hadoop classpaths, but it can
+happen that the Hadoop dependencies must be in the classpath when
submitting a
+job to YARN. For this, it's usually enough to do a
+
+```
+export HADOOP_CLASSPATH=`hadoop classpath`

> URL: https://issues.apache.org/jira/browse/FLINK-8668
> Project: Flink
> Issue Type: New Feature
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Major
> Fix For: 1.5.0
>
>
> Automatically adding this when available can lead to dependency problems for
> some users and there is no way of turning of this "feature". It was added to
> make using Flink on AWS/EMR and GCE a bit easier but I think it's causing
> more harm than good.
> If users want to to augment the classpath they can always {{export
> HADOOP_CLASSPATH=...}}.
