Subject [jira] [Updated] (HAMA-443) SSSP doesn't works with multi-tasks
Date Thu, 10 Nov 2011 14:31:52 GMT

     [ https://issues.apache.org/jira/browse/HAMA-443?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas Jungblut updated HAMA-443:
---------------------------------

    Attachment: HAMA-443_v2.patch

sssp fully works now.

But we have to define when to let the splitter do its job by defining the task size and when
to use the number of tasks the user defines /available in the cluster.

It is a total mess currently.
