Subject [jira] [Commented] (GIRAPH-601) Exception when running pagerank benchmark: SendVertexRequest cannot be cast to MasterRequest
Date Fri, 29 Mar 2013 21:03:15 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13617717#comment-13617717

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

Yes, I think somehow the configuration setting is not being respected even though I'm seeing
"split master/worker = true" in the console output:
