Subject [jira] [Commented] (MAPREDUCE-4393) PaaS on YARN: an YARN application to demonstrate that YARN can be used as a PaaS
Date Wed, 11 Jul 2012 20:01:36 GMT

Kihwal Lee commented on MAPREDUCE-4393:
---------------------------------------

You have probably done it already, but the first thing to make sure is that everything builds
okay for all targets and profiles. e.g. build and run test with clover (-Pclover). The test-patch
process is most useful when existing code is modified, so in your case it would be nice if
you could report more testing results.

People will also like to hear about your experience on writing a new YARN app.  There are
on-going works to make it easier to develop and debug apps. I am sure these efforts will benefit
from your input.

> This application is to demonstrate that YARN can be used for non-mapreduce applications.
As Hadoop has already been adopted and deployed widely and its deployment in future will be
highly increased, we thought that it's a good potential to be used as PaaS.  
> I have implemented a proof of concept to demonstrate that YARN can be used as a PaaS
(Platform as a Service). I have done a gap analysis against VMware's Cloud Foundry and tried
to achieve as many PaaS functionalities as possible on YARN.
> I'd like to check in this POC as a YARN example application.
