Subject a few questions
Date Fri, 09 Nov 2012 16:13:35 GMT

A few questions please.

1. When I tried to run Oozie examples I was told to copy to copy /examples folder into HDFS.
However when I tried to run oozie job I was told that the source file was not found. Well,
until I cd'ed into the local directory on Linux and re-run the job successfully.
What was the point copying the examples into HDFS if they are started from local Linux FS.
This opens up a similar question. When I create my jobs I run .jar file from local FS and
not from HDFS.  I have though that was the way. Can you actually tell hadoop where to run
the MR job from: local or HDFS?

2. I noticed that Linux created group "hadoop" and adds hdfs/mapreduce user to it after the
installation. However, inside HDFS the group is called "supergroup". Can someone elaborate
on that?
