We are building a system with hadoop mapreq as the back-end
distributing-computing engine.  The front-end is also in java.  So it will
be nice to start a hadoop job, or interact with hdfs directly within java,
not invoking the hadoop script.  Is there any tutorial or guide for this?
Otherwise, I have to read through all the hadoop script to simulate the
proper setting.  Thank you very much.

Yes you can this.  Take a look at JobClient.runJob and JobClient.submitJob.

Hi,

This has been asked a few times before. See:

that'll help.
