Date Mon, 11 Mar 2013 14:07:12 GMT

    [ https://issues.apache.org/jira/browse/HAMA-744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13598833#comment-13598833

Edward J. Yoon commented on HAMA-744:
-------------------------------------

If the former, there are two options: 1) use of sorted queue 2) tree set and merge sorted
files.

1) looks more fault tolerant approach. 
2) can faster than 1).

> Summary:
>  * Error occurs on generated data by sym-mat gen or fastgen 
>  * HAMA-704 requires sorted input.
> I'm not sure whether partitioned input data need to be Sorted by default. It should be
configurable, or Should we change the VerticesInfo?
