Avery Ching commented on GIRAPH-737: ------------------------------------ You're the expert on YARN and Giraph Eli! =) > 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. > -- This message was sent by Atlassian JIRA (v6.1#6144)
