Subject [jira] [Updated] (GIRAPH-136) Erorr message for bin/giraph could be improved
Date Wed, 01 Feb 2012 02:08:56 GMT


Jakob Homan updated GIRAPH-136:

    Attachment: GIRAPH-136.patch

Patch that chastises no-arg invocations thusly:
{noformat}tardis s003 ~/repos/giraph> bin/giraph
Usage: giraph [-D<Hadoop property>] <jar containing vertex> <parameters to
At a minimum one must provide a path to the jar containing the vertex to be executed.{noformat}

I didn't enumerate all the parameters since that would be duplicating information provided
by GiraphRunner.
