Subject [jira] [Updated] (GIRAPH-228) SimpleTriangleClosingVertex should not use ArrayWritable for a vertex value
Date Mon, 02 Jul 2012 01:29:45 GMT

     [ https://issues.apache.org/jira/browse/GIRAPH-228?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eli Reisman updated GIRAPH-228:
-------------------------------

    Attachment: GIRAPH-228-1.patch

Changed Vertex Value to Text for storage of final results. Had trouble getting IO formats
to work with ArrayWritables of any sort I tried (see separate JIRA) this passes mvn verify
and has been run successfully. Adds another unit test to the version in GIRAPH-217.

> Need to convert to (yuck) Text output for vertex values, hope my tuples don't get too
long. I followed several instructions from Hadoop about subclassing and using existing ArrayWritables,
always both methods will compile with 'mvn verify' nicely, but break in actual use. GiraphJob.run()
seems to be the culprit. Don't know if I can solve this myself in a way that will be pleasing
to everyone. See GIRAPH-227 if you can help fix this ArrayWritable problem. As far as the
vertex example, I'll covert it (and related tests) to Text output now.
> Thanks again to Sean Choi, who noticed this and used the same (Text for tuples) solution
successfully. ;)
