Subject [jira] [Commented] (MAPREDUCE-2600) MR-279: simplify the jars
Date Thu, 11 Aug 2011 09:12:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13083026#comment-13083026

Luke Lu commented on MAPREDUCE-2600:
------------------------------------

bq. If no of jars is the problem, can we just merge the jars at build time the way we want.
Using maven shade plugin or some such ?

I agree with Sharad, the current modules layout is fine. It makes working on individual features
faster and easier. People who complain about number of source roots should improve their IDE
fu and/or use a better IDE, IMO :)

According to recent conversations with people involved, I got the impression that it's just
a packaging issue, i.e., having 3 combined jars plus dependencies in the distribution tar
ball. yarn-client, yarn-servers and hadoop-mapreduce. So just some maven-shade-plugin fu would
suffice.

> Currently the MR-279 mapreduce project generates 59 jars from 59 source roots, which
can be dramatically simplified.
