Question about ec2 script

Hi,

I found one little mistake in In the hbase-ec2-init-remote.sh:
# Update classpath to include HBase jars and config
cat >> $HADOOP_HOME/conf/hadoop-env.sh <<EOF
HADOOP_CLASSPATH="$HBASE_HOME/hbase-${HBASE_VERSION}.jar:$HBASE_HOME/lib/AgileJSON-2009-03-30.jar:$HBASE_HOME/lib/json.jar:$HBASE_HOME/lib/zookeeper-3.2.1.jar:$HBASE_HOME/conf"
EOF

${HBASE_VERSION} seem's undefine here.
I simply add a line: HBASE_VERSION=`echo $HBASE_HOME | cut -d '-' -f 2`
before that block, and that's work correctly (although this is not a good
way :P).

Besides, I have a small question:
How can I re-start my Hadoop/HBase cluster through the ec2 script or the
other easy way?

Thanks a lot!

Thanks for the feedback.

This works, so that's ok with me. I committed your suggestion. The Hadoop EC2 scripts, at least the old ones, do something similar.

The scripts can only do a full restart:

    ./bin/hbase-ec2 terminate-cluster <name>
    ./bin/hbase-ec2 launch-cluster <name> <slaves> <zoos>

You can also log on to the master and use the HBase control scripts:

    ./bin/hbase-ec2 login <name>
    $ cd /usr/local/hbase*
    $ ./bin/stop-hbase.sh
    $ ./bin/start-hbase.sh

but before that would work you must manually update /usr/local/hbase*/conf/regionservers with all of the internal DNS names of your cluster slaves.
