[jira] [Commented] (TINKERPOP3-801) groupCount() fails for vertices (elements?) (using Spark)

["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP3-801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14876204#comment-14876204 ] 

Marko A. Rodriguez commented on TINKERPOP3-801:
-----------------------------------------------

This is NOT a Kryo version conflict like a I suspected. This is due to the fact that {{ComputerGraph.ComputerVertex}} is being put into Spark's KryoSerializer and what REALLY needs to be put there is {{StarGraph.StarVertex}}. This is easily solved by writing a custom serializer, but then at that point we should really be using Gryo serializers in Spark-Gremlin.... [~spmallette] is looking into a solution for allowing us to get the shaded Kryo of Gryo exposed as native Kryo in Spark-Gremlin. .... dar.

I can solve this in both 3.0.2 and 3.1.0 so if the "Gryo exposure" can happen in 3.0.2, that would be great.
