> Giraph was the early adopter of Hadoop YARN AM! Eli successfully wrote a
> Giraph AM based on Hadoop 2.0.x_alpha. However, in last few months, Yarn
> significantly *overhauled* its APIs and associated coding patterns. The new
> beta version is 2.1.x and I was told by Yarn-dev that current APIs will not
> change much.
> In the above circumstances, we need to substantially overhaul Giraph AM as
> well to accommodate with the new Yarn API. Moreover, in newer YARN API,
> supporting kerberos security in AM becomes easier and more transparent.
> Potential impact:
> The upcoming Girpah AM will not work with earlier alpha Hadoop versions such
> as 2.0.3. I'm not sure if anyone is using Giraph AM in production. However,
> the more prevalent way of Giraph processing (MR-based) should continue to
> work.
