I used ec2, but just for experiments. Here is what I did:
a) used the ephemeral disks. My experiment datasets were persisted on S3,
and I copied them onto the cluster.
b) Use the hbase-ec2 scripts. get this repo
c) Consult Andrew's pdf: hbase.s3.amazonaws.com/hbase/HBase-EC2-HUG9.pdf
For the AMI, there is a create-hbase-image script in the above git repo. I
did create for my stuff and it's public, search "himanshu-hbase" and you
should get it. But it's always good to have your own AMI (I learned it the
Consult the run scripts, like bin/launch-hbase-cluster,
One thing was when you run the launch-cluster, the cluster is all set but I
needed to manually add the regionserver's internal ip in the master's
conf/regionserver list. And also the datanode's entry in the conf/slaves if
hadoop directory. This can be done by a script though.
Hope this helps.
