--------------------------------------------
Summary: Giraph Application Master: move to new and stable YARN API
Key: GIRAPH-737
URL: https://issues.apache.org/jira/browse/GIRAPH-737
Project: Giraph
Issue Type: New Feature
Components: mapreduce
Reporter: Mohammad Kamrul Islam
Assignee: Mohammad Kamrul Islam
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.
