Subject HBase EdgeInputFormat
Date Thu, 18 Jul 2013 14:49:51 GMT

Question: Will there be HBaseEdgeInputFormat class or is there a restriction of HBase thus
we can't implement it?

HBaseVertexInputFormat is fine for vertex-centric reading, i.e. each row in HBase corresponds
to one Vertex. But it does not allow me to create duplicate vertices with the same ID.
Now I have the case "many rows in HBase can correspond to one Vertex, each representing sets
of edges."

a1 - x y z
a2 - t p
a3 - k

will be

vertex "a" with edges to x y z t p k

It gives me the intuition that if there existed HBaseEdgeInputFormat, I could solve this case.
But it doesn't exist yet.
