Subject [jira] [Updated] (HAMA-838) Add custom aggregators
Date Tue, 07 Jan 2014 01:15:51 GMT

     [ https://issues.apache.org/jira/browse/HAMA-838?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Edward J. Yoon updated HAMA-838:
--------------------------------

    Attachment: HAMA-838_v02.patch

I've changed few minor things.

-pageJob.registerAggregator("avg", AverageAggregator.class);
+pageJob.registerAggregator(AVG_AGGREGATOR, AverageAggregator.class);

Moved CustomAggregator example to unit test. We currently have too many examples I think.

And, please use our code-format in the future. You can download here - http://hama.apache.org/developers.html
