Subject [jira] [Commented] (HAMA-833) Add more finish states for vertices
Date Mon, 23 Dec 2013 13:38:50 GMT

    [ https://issues.apache.org/jira/browse/HAMA-833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13855636#comment-13855636

Ilias Kapouranis commented on HAMA-833:
---------------------------------------

Insted of getLastAggregatedValue(0) use getNumLastAggregatedVertices(0).

I know that he doesn't get called and this is right. But he gets aggregated at 1 superstep!
My test code is the one pasted. And one line in which initializes the vertex values.

> We should handle more cases on the vertices, like:
> 1) voteToStop() : Immediately stop the vertex compute and suppress any further calculations
on top of that. (e.g. aggregation)
> 2) voteToTerminate(): Immediately stop the vertex compute, suppress any further calculations
on top of that and deactivate the vertex so even if any message reaches it, will not come
alive.
> Any comments?
