Subject [jira] [Commented] (HAMA-443) SSSP doesn't works with multi-tasks
Date Fri, 11 Nov 2011 00:33:51 GMT

    [ https://issues.apache.org/jira/browse/HAMA-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13148160#comment-13148160
] 

Edward J. Yoon commented on HAMA-443:
-------------------------------------

As I asked before, what happens if tasks size is bigger than hard-coded 16 nodes?

Let's just remove hard-coded data. And the usage should be printed only if args.length <
3.
