Subject [jira] Commented: (PIG-1452) to remove hadoop20.jar from lib and use hadoop from the apache maven repo.
Date Tue, 03 Aug 2010 21:31:17 GMT

    [ https://issues.apache.org/jira/browse/PIG-1452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12895045#action_12895045

Daniel Dai commented on PIG-1452:
---------------------------------

hsqldb.jar is pulled by Pig only for unit test. I am not sure if hadoop also depend on it
or not, if that's the case, then we should retain it. For those transient dependencies, can
we exclude them from pig.jar? Some jars such as core-3.1.1.jar is really big. Since pig.jar
will be shipped to every backend node, we really want to keep it smaller.

> pig use ivy for dependency management. But still it uses hadoop20.jar from the lib folder.

> Now that we have the hadoop-0.20.2 artifacts available in the maven repo, pig should
leverage ivy for resolving/retrieving hadoop artifacts.
