Jens Rabe created YARN-3135: ------------------------------- Summary: There should be an easier way to submit Java-based YARN applications Key: YARN-3135 URL: https://issues.apache.org/jira/browse/YARN-3135 Project: Hadoop YARN Issue Type: Improvement Components: api Reporter: Jens Rabe
Since YARN is designed to not only work with Java, it is quite difficult and cumbersome to correctly setup a YARN application. For Java-based ones, it should be easier; there should be something like the MR2 Job API. My proposal is the following: # Have a basic Job / Application object, e.g. YarnApplication, which could be instantiated and configured the following: {code:java} final Configuration conf = ... final YarnApplication app = YarnApplication.getInstance(conf); app.setContainerClassName(MyContainer.class); app.setJarByClass(MyContainer.class); {code} # There should be a means to send and receive messages between container and AppMaster # The container should be able to report progress and state to the AppMaster # Bonus: A simplified WebAppMaster should start a web application and have its URL automatically proxied when run -- This message was sent by Atlassian JIRA (v6.3.4#6332)
