Subject [jira] [Commented] (HAMA-700) BSPPartitioner should be configurable to be optional and allow input format conversion
Date Mon, 17 Dec 2012 11:26:12 GMT

    [ https://issues.apache.org/jira/browse/HAMA-700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13533857#comment-13533857
] 

Edward J. Yoon commented on HAMA-700:
-------------------------------------

Your approach is that, 1) writes converted record to a split, 2) and then each GraphJobRunner
task just reads vertices from assigned split. So, there's no way to avoid writing every records
to a files when the input is a table of NoSQL. Right? If so, this issue should be closed as
a "won't fix".

> There should be a provisioning for skipping the PartitionRunner if needed. Also we can
have a RecordConverter interface so that the PartitionRunner can read the input in any format
and create new splits.
