------------------------------------------------------------

Overall, it looks great! 
Some notes:
* Any reason to set hadoop.tmp.dir to /var/lib/hdfs/cache/${user.name} instead of /var/lib/hdfs/cache/${user.name}/tmp ? 
* I don't really like moving /usr/libexec to /usr/lib/hadoop/libexec. But if it makes it work, I don't really have choice.
* Where does ${bin_wrapper/hadoop/yarn} come from?
* I would set hdfs user's homedir to /var/lib/hdfs. Same for other users (I know it's not new)
* the %preun in hdfs, yarn and mapreduce in the spec file won't work. the %service_macro will take care of that. So please delete these sections.

> Here are the new names I would like to propose in hadoop-0.23 branch:
>  * hadoop (for hadoop-common, but since it won't be limited to just the hadoop-common project it is hadoop)
>  * hadoop-hdfs
>  * hadoop-yarn
>  * hadoop-mapreduce
>  * hadoop-hdfs-namenode
>  * hadoop-hdfs-secondarynamenode
>  * hadoop-hdfs-datanode
>  * hadoop-yarn-resourcemanager
>  * hadoop-yarn-nodemanager
>  * hadoop-mapreduce-historyserver
>  * hadoop-libhdfs
>  * hadoop-conf-pseudo
>  * hadoop-docs
> given that they look a tad too long, an alternative would be to drop hadoop- prefix and go with
> the shorter versions (even though technically all these projects are *sub* projects of Hadoop):
>  * hadoop
>  * hadoop-conf-pseudo
>  * hadoop-docs
>  * hdfs
>  * yarn
>  * mapreduce
>  * hdfs-namenode
>  * hdfs-secondarynamenode
>  * hdfs-datanode
>  * yarn-resourcemanager
>  * yarn-nodemanager
>  * mapreduce-historyserver
>  * libhdfs
>  * hadoop-conf-pseudo
>  * hadoop-docs
> Please leave your opinion on which one is better in the comments section.
> P.S. Quick search over at http://pkgs.org revealed no name clashes for both
> long and short versions.
