Subject SequenceFileVertexInputFormatClass
Date Tue, 16 Jul 2013 21:05:42 GMT
Does anyone have a simple example of how to use it?  Do I need to extend it
for my classes or can I just use it like I would

SequenceFileInputFormat in hadoop.  I'm getting the following error;

But I think the input path is correctly set.  Thanks, I appreciate it,
