I've built pig-withouthadoop.jar and have copied it to my linux box.
Now how do I put hadoop-core-0.20.203.0.jar and pig-withouthadoop.jar
in the classpath. Is it by using CLASSPATH variable?

I added all the jars in the classpath in HADOOP_HOME/lib and now I get
to the grunt prompt. Will try the tutorials and see how it behaves :)
Thanks for your help!

How can I tell how the map and reduce tasks were spread accross the
cluster? I looked at the jobtracker web page but can't find that info.
Also, can I specify how many map or reduce tasks I want to be launched?
From what I understand is that it's based on the number of input files
passed to

Hi Mohit,
No of Maps - It depends on what is the Total File Size / Block Size
No of Reducers - You can specify.

can I change this to distribute accross multiple machines?

word count but I still lack knowledge of some important features.

I just started learning hadoop and got done with wordcount mapreduce

Some questions
1) What should be my first step now? Are there more examples
somewhere that I can try out?
2) Second question is around pracitcal usability using xml files. Our

Sorry for all the questions. I am new and trying to get a grasp and
also learn how would I actually solve our use case.

Is hadoop going to format entire file sytem when I run bin/hadoop
namenode -format?
For eg: I have mountpoint /data and there are other files in /data
But I created a directory hadoop inside /data. Now if I run namenode
-format would it format everything inside /data or can I tell it to
format
Is there any specific reason for this logic in hadoop file under bin
where it checks for EUID? Whenever I start-dfs.sh it goes in -jvm
server if block and my jvm doesn't support that option.
elif [ $COMMAND = datanode ] ; then
CLASS='org.apache.hadoop.hdfs.server.datanode.DataNode'
