Subject [jira] [Commented] (GIRAPH-601) Exception when running pagerank benchmark: SendVertexRequest cannot be cast to MasterRequest
Date Fri, 29 Mar 2013 20:45:16 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13617701#comment-13617701

Eugene Koontz commented on GIRAPH-601:
--------------------------------------

Hi Maja,
Thanks for the suggestion. It seems that the job still doesn't finish even with removing that
line. Also, I'm running with no giraph.SplitMasterWorker setting, so it should default to
true. 
Still digging.. :)
