Review request for giraph.
Bugs: GIRAPH-737
https://issues.apache.org/jira/browse/GIRAPH-737
Repository: giraph-git
Description
-------
WIP patch. Please give your early comments.
Key points:
* Giraph AM using new API and asynchronous/handler model.
* Adding Kerberos support.
Copied from the JIRA:
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.
