cc/ [~Sreenath]
> Investigate Java 7 compatibility for new YARN UI
> ------------------------------------------------
>
> Key: YARN-6293
> URL: https://issues.apache.org/jira/browse/YARN-6293
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Li Lu
>
> Right now when trying the YARN new UI with Java 7, I can get the following
> warning:
> {code}
> [INFO] --- maven-enforcer-plugin:1.4.1:enforce (dist-enforce) @
> hadoop-yarn-ui ---
> [WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireJavaVersion failed
> with message:
> Detected JDK Version: 1.7.0-67 is not in the allowed range [1.8,).
> {code}
> While right now this warning does not cause any troubles for trunk
> integration, when some users would like to package the new UI with some
> branch-2 based code, the JDK requirement would block the effort. So the
> question here is, is there any specific component in new UI codebase that
> prevent us using Java 7? I remember it should be a JS based implementation,
> right?
