Jason Lowe commented on HADOOP-9397:
------------------------------------
Thanks for looking into this, Chris. I'm assuming this was changed because
some platform doesn't support the 'z' flag for {{tar}}. Curious though, why
does hadoop-dist invoke tar and gzip separately, while other projects pipe the
output of tar to gzip (e.g.: hadoop-mapreduce-project, hadoop-yarn-project)?
The latter doesn't have this issue because the shell redirect clobbers the
output file. Do we really need the intermediate .tar file kept around?
