[jira] [Commented] (GIRAPH-355) Partition.readFields crashes

    [ https://issues.apache.org/jira/browse/GIRAPH-355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13467497#comment-13467497 ] 

Avery Ching commented on GIRAPH-355:
------------------------------------

This is fixable if Partition takes a Progressable input and calls progress from there rather than using the vertex progress.  Do you have a failure case that we can look at?

> Partition:157 (vertex.getContext().progress();) will crash since graphState for vertex is null at this point. We need to get Context inside Partition in order to be able to call progress here. 
> The reason why this wasn't noticed is that our local tests don't try checkpoint restart at the moment, and that's the only place where Partition.readFields is called.
