[Bigdata-developers] [Blazegraph] First somewhat amusing trial on blueprints

[Jack P. <jac...@gm...>]

I created a gist here:
https://gist.github.com/KnowledgeGarden/87ac9991cafc69d179e1

The gist shows two bodies of code:

My embedded driver code; rather spartan, but something to get started, by
copying code found on the web and in blueprints unit tests.

My test code, copied from blueprints unit tests, which loads one of the
simple blueprinits properties graphs and prints the vertex and edge lists.

Included is the output trace of the first test, which shows that it does,
indeed, load the graph and print. But, no journal document is created; the
data folder is empty.

Included below that is the output trace where I hand-created the journal.
It promptly ballooned to 10,240kb, which, I presume, means that a graph was
loading into it along with other stuff, but it crashed apparently while
doing the graph import.  The link into my code points to this line:

GraphMLReader.inputGraph(graph, example);

It is simply not clear to me what is going on here.

Thanks in advance for some ideas.
