[jira] [Commented] (YARN-3172) MR-279: Write a simple Java application

    [ https://issues.apache.org/jira/browse/YARN-3172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14342041#comment-14342041 ] 

Allen Wittenauer commented on YARN-3172:
----------------------------------------

This has been open for about 3 years with a lot of people watching.  It still applies.  

Do we feel that the distributed shell example is good enough?  Would it benefit the community to also have this committed along side of it?  Or does Slider, et. al., fill the original need here?

We should make a decision in the next week:  commit or close.

> Currently for isolation purposes, many simple java applications run in cluster with 1 map only job. (eg. Oozie). This is not really required with nextgen hadoop (mrv2) and *non-MR* apps are first class and easy to write.
> A simple hadoop java app can be written which runs in the cluster in the user space.
