Subject [jira] [Commented] (HADOOP-8035) Hadoop Maven build is inefficient and runs phases redundantly
Date Wed, 08 Feb 2012 21:17:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13203994#comment-13203994
] 

Andrew Bayer commented on HADOOP-8035:
--------------------------------------

Ok, I think this is because hadoop-project-dist/pom.xml expects things like src/main/docs
to be present in the project inheriting from it, and unlike the other two cases of inheriting
from hadoop-project-dist (hadoop-common-project/hadoop-common and hadoop-hdfs-project/hadoop-hdfs),
hadoop-tools/hadoop-tools-dist is an empty project. But I'm not sure why it's even trying
- theoretically, it wouldn't run if "is.hadoop.component" is false, but I think that may only
function if "is.hadoop.component" isn't set at all.

> The Hadoop 0.23 Maven build has some major inefficiencies, most notably in site and javadoc.
As a result of redundant plugin executions and certain plugin executions being inherited when
they really shouldn't be, builds take a lot longer than they should.
