Subject [jira] [Commented] (GIRAPH-182) Provide SequenceFileVertexOutputFormat as an available OutputFormat
Date Wed, 11 Apr 2012 20:13:16 GMT


Jakob Homan commented on GIRAPH-182:

Hey Pradeep. Thanks for the contribution.
* Apache prohibits author tags to ensure that all the code is viewed as the whole community's
* SimpleSequenceFileVertexOutputFormat: We've thus far had the convention of using the type
names in the in/outputformats. This is a bit verbose and may not be the right approach, but
it's probably best to keep it in this patch.  Also can you provide javadoc for it?
* SequenceFileVertexOutputFormat: Any reason not to use the more standard M type variable?
Some Javadoc for the class would be nice here too.
* Is it possible to add a unit test just to verify we get out from the file what we put in?

> SequenceFile's are heavily used in Hadoop. We should provide SequenceFileVertexOutputFormat.
Since SequenceFileVertexInputFormat is already provided, it makes sense to also provide a
mirroring OutputFormat
