[jira] [Updated] (SPARK-6169) Shuffle based join
[ https://issues.apache.org/jira/browse/SPARK-6169?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen updated SPARK-6169:
-----------------------------
Component/s: Shuffle
Description:
Leverage improved spark shuffle to do the join more efficiently - the current impl using cogroup can be significantly improved.
I wont be able to work/contribute on this unfortunately, would be great if someone else can pick this up - wanted to ensure this task is not missed out.

Can you elaborate this, especially if you're not going to work on it? What do you think needs to use a different shuffle?
