Subject [jira] Commented: (MAPREDUCE-1478) Separate the mapred.lib and mapreduce.lib classes to a different jar and include the user jar ahead of the lib jar.
Date Wed, 10 Feb 2010 22:30:36 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12832254#action_12832254
] 

Arun C Murthy commented on MAPREDUCE-1478:
------------------------------------------

We also need to load the mapreduce.lib jar after loading the user-jars. Currently we load
the system jars and then user jars, so the new order would be:

system-jars, user.libs, mapreduce.lib.

> Separate the mapred.lib and mapreduce.lib classes to a different jar and include the
user jar ahead of the lib jar.

> Currently the user can't include updated library jars as part of their job. By pulling
out the lib classes we can include the classes (eg. TextInputFormat) in the user's jar and
get their version and not the system installed one.
