Description

The conf directory situation in the tarball (generated by mvn pacakge -Dtar) is a mess. The top-level conf directory just contains mr2 conf, there are two other incomplete conf dirs:

hadoop-0.24.0-SNAPSHOT $ ls conf/
slaves  yarn-env.sh  yarn-site.xml
hadoop-0.24.0-SNAPSHOT $ find . -name conf
./conf
./share/hadoop/hdfs/templates/conf
./share/hadoop/common/templates/conf

yet there are 4 hdfs-site.xml files:

hadoop-0.24.0-SNAPSHOT $ find . -name hdfs-site.xml
./etc/hadoop/hdfs-site.xml
./share/hadoop/hdfs/templates/conf/hdfs-site.xml
./share/hadoop/hdfs/templates/hdfs-site.xml
./share/hadoop/common/templates/conf/hdfs-site.xml

And it looks like ./share/hadoop/common/templates/conf contains the old MR1 style conf (eg mapred-site.xml).

We should generate a tarball with a single conf directory that just has common, hdfs and mr2 confs.
