Avery Ching commented on GIRAPH-387:
------------------------------------
Not sure why, but we got a session expired event from the test. Restarted the
build and it passed fine.
One of these days we should fix the below problem.

[INFO] ------------------------------------------------------------------------
> GiraphRunner's better handling of configuration property arguments
> ------------------------------------------------------------------
>
> Key: GIRAPH-387
> URL: https://issues.apache.org/jira/browse/GIRAPH-387
> Project: Giraph
> Issue Type: Improvement
> Reporter: Jaeho Shin
> Assignee: Jaeho Shin
> Priority: Minor
> Attachments: GIRAPH-387-2.patch, GIRAPH-387.patch
>
>
> After GiraphConfiguration came along (GIRAPH-337?), GiraphRunner started to
> forget all configuration properties passed as -D arguments, and picked up by
> ToolRunner. I'm submitting a one-line fix for that, plus a small improvement
> to GiraphRunner's {{-ca}} option.
> Previously, to pass multiple custom arguments over the {{-ca}} option, we had
> to join all the name=value pairs with comma and only the last one had effect.
> This was not so practical for many of my use cases, so I made some change to
> GiraphRunner that let us use as many {{-ca}} options as we want.
