Thomas Jungblut updated HAMA-423:
---------------------------------
Attachment: HAMA-423-v1.patch
I really did a lot of stuff here.
But partitioning will now take about 1 minute for our example files.
I'm going to extend the wiki. Currently I am uploading the new .txt example
files to trunk.

> Currently partitioning will write a key/value pair for each vertex/adjacent
> mapping.
> This results in heavy IO writes which actually bloats the file and let the
> partitioning take unnecessarily long.
> We should partition directly into the vertex classes and implement a vertex
> list/array writable which just writes a single key/value pair for a
> vertex/all-adjacents mapping.
> In fact we should make it generic, passing a vertex class which should
> implement the Writable interface.
