Did that, but given that I was trying to run against 2.0.0-alpha I also had=
 to
manually adjust the version. Perhaps now that 2.0.0-alpha is out it would
be useful to adjust the giraph profile to bind to that version instead of 0=
.23.

Anyway, I can now successfully submit the giraph job, but the job can't
complete. In fact I see that 3 maps failed with the following. And the rema=
ining
4 maps just refuse to exit (hence the job hangs).

Does this look like a known issue or should I file a JIRA?
