I think so. +1 for the patch, all the unit tests passed!

> Currently, GraphJobMessage comparation opertion depends on the default
> comparator (org.apache.hadoop.io.WritableComparator used), which has to read
> out all GraphJobMessage message (including vertexId and vertexValue) when
> does the comparation.
> Since lots of comparation operations happen in graph computing, this
> limitation makes a performance downgrade.
