Hey Craig/Sebastian.

Great to see that you guys are testing out our new Hadoop port!

Once you have built mesos-hadoop, there should be a "hadoop.tar.gz" package
inside the hadoop build directory
(e.g. mesos/build/hadoop/hadoop-2.0.0-mr1-cdh4.1.2/build)

This should contain all the stuff that is need to run the Mesosified Hadoop
JobTracker and TaskTracker.

In your case, I would suggest just copying this bundle to wherever you want
to run the Hadoop JobTracker, unzip it and run "bin/hadoop/jobtracker".

Some important info:

--> Before running the jobtracker, make sure to edit "conf/mapred-site.xml"
to the correct values.

--> Specifically, you might want to set "mapred.mesos.master" to the URL of
your Mesos Master (e.g. 1.2.3.4:5050).

--> You also need to upload the hadoop.tar.gz to a location where Mesos
slaves can pull it (e.g. http://<ip>/hadoop.tar.gz), to run the Hadoop
TaskTracker.

Let me know if that makes sense and if you have any further questions.

Cheers,



@vinodkone
