Hi Johannes,
> i'm using the 0.16.0 distribution.
I assume you mean the 0.16.0 release
(http://hadoop.apache.org/core/releases.html) without any additional patch.
I just have tried it but cannot reproduce the problem you described. I did the
following:
1) start a cluster with "tsz"
2) run a job with "nicholas"
The output directory and files are owned by "nicholas". Am I doing the same
thing you did? Could you try again?
