> The DiskBackedPartitionStore is throwing an NPE when trying to load a
> partition from disk. It seems to be related to the call to
> ImmutableClassesGiraphConfiguration.createOutEdges() which doesn't initialize
> the OutEdges before it attempts to populate them via Vertex.initialize().
> Simply switching to
> ImmutableClassesGiraphConfiguration.createAndInitializeOutEdges() seems to
> correct the following stack trace:
> Caused by: java.lang.NullPointerException
