Subject Re: Problem with simple shortest path
Date Sun, 19 Jul 2015 14:56:50 GMT
Hello again

The fix I suggested for the IllegalArgumentException in your output. The Edge input and output
format missing warning is not an error, is reminder that you did not specify them (in fact
they are classified as INFO, not ERROR nor WARN).

To better understand how the I/O works in Giraph, I suggest you read the “Main Interfaces”
paragraph in http://giraph.apache.org/io.html <http://giraph.apache.org/io.html>.

Hope this helps.
