Subject [jira] Commented: (MAPREDUCE-1026) Shuffle should be secure
Date Tue, 22 Sep 2009 23:15:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758477#action_12758477

Jeff Hammerbacher commented on MAPREDUCE-1026:
----------------------------------------------

Hey Owen (and probably Doug),

While we're here: how would this strategy change if map output was transferred to the reducers
using Avro's RPC? Is there authentication in the handshake, and encryption (ssl?) for the
data?

Just trying to educate myself for The Future (tm).

Thanks,
Jeff

> Since the user's data is available via http from the TaskTrackers, we should require
a job-specific secret to access it.
