Subject [jira] [Commented] (MAPREDUCE-279) Map-Reduce 2.0
Date Mon, 21 Mar 2011 15:50:08 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009183#comment-13009183

Arun C Murthy commented on MAPREDUCE-279:

bq. Looking through the code a bit more I came across Hamlet.

Luke can provide more details, but I believe he took this route due to the lack of a better
'embeddable' alternative.

Having said that, echo'ing eric14, please feel free to open a jira with an alternate proposal
and we can consider moving over to something more standard that satisfies our constraints.
Alternately, in the long run, we could move Hamlet out to a separate (incubator?) project
to attempt build a community around.
