The only way we've found to write an application master is by example. However, the distributed-shell example in 2.2 was not very good; it is much improved in 2.4. I would start with that and edit, rather than create from scratch.

I'm trying to write my first YARN application using a doc http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/WritingYarnApplications.html . This page is said to describe Apache Hadoop 2.3.0. But a method ``appMasterRequest.setApplicationAttemptId(appAttemptID);`` mentioned there was removed about a year ago https://issues.apache.org/jira/browse/YARN-918 , so "Writing Yarn Application" is not actual. How can I help with actualizing documentation? Thank you! -- Konstantin Nikitin Software engineer
