> Basically, SequenceFileVertexInputFormat has WritableComparable<I> as a bounded
type for I, while the Hadoop serializable data types implement WritableComparable. Because
of this, I suspect TextVertexInputFormat only has WritableComparable as a bounded type for
I and has a SuppressWarnings("rawtypes") annotation. I think SequenceFileVertexInputFormat
should follow the same style, otherwise it's not possible to use, for example, IntComparable
as vertex id type in a SequenceVertexInputFormat.
