-------------------------------------
Summary: Add warning to the YARN client when using an older Hadoop
version
Key: FLINK-2581
URL: https://issues.apache.org/jira/browse/FLINK-2581
Project: Flink
Issue Type: Improvement
Components: YARN Client
Affects Versions: 0.10
Reporter: Robert Metzger
Assignee: Robert Metzger
Some users were facing issues when using Flink on YARN because they were using
outdated Hadoop releases included into Flink.
In this example, the user was using Flink with hadoop 2.2.0 included, against a
Hadoop 2.6.0 cluster:

With this change, I'm going to ResourceManager's REST API to get the Hadoop
version of the remote YARN cluster:

This Hadoop class allows us to determine the local Hadoop version we are using:
