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.
