---------------------------
Summary: 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?
