SSSP doesn't work
Hello,
I have a Hama-0.6.0 on a Hadoop-1.0.4. I am running in the Pseudo
Distributed Mode.
The example SSSP always returns 2147483647 as the shortest distance to each
vertex.
This is the input file.
=====
one\ttwo:1
two\tone:1
=====
This is the command line.
=====
<Hama root>/bin/hama jar hama-examples-0.6.0.jar sssp two <path to the
input file on the local file system> <path to the output directory on the
local file system> 1
=====
This is the shell prompt.

=====
This is the output file.
=====
one\ttwo:1 2147483647
two\tone:1 2147483647
=====
What may go wrong? Do I miss anything?
Many thanks,

it seems failed to parse vertices correctly. Please check the
parseVertex() method.
