Hi everybody,

I have created a cluster hadoop (When create Node group template, I have
modified mapred.child.java.opts: "-Xmx200m" to "-Xmx1024m"). Then i ssh to
master-instance and run: "hadoop jar hadoop-examples-1.2.1.jar pi 10 100",
I get the error:
java.lang.OutOfMemoryError: Java heap space

Check file /etc/hadoop/hadoop-env.sh. I see:
Default: export HADOOP_CLIENT_OPTS="-Xmx128m HADOOP_CLIENT_OPTS"

Then, I edit 128 to 1024:
export HADOOP_CLIENT_OPTS="-Xmx1024m $HADOOP_CLIENT_OPTS"

When run "hadoop jar hadoop-examples-1.2.1.jar pi 10 100", it's worked!
But, my cluster still in a state: "Watting" and
ip_master:50030/jobtracker.jps not running?

Why HADOOP_CLIENT_OPTS in /etc/hadoop/hadoop-env.sh not automatic update
when create cluster?

What is the problem here? Thank you very much!
