Subject Re: JobClient using deprecated JobConf
Date Wed, 22 Sep 2010 17:59:59 GMT
David,

This was discussed here:
http://www.mail-archive.com/mapreduce-dev@hadoop.apache.org/msg01833.html.
The reason is basically to give users more time to move to the new
API. The old API will be marked as deprecated in 0.22.0.

Cheers,
Tom
