'lost connection' is a SSH problem.

Did you set up a SSH private key on your AWS/EC2 account named "root"?

Did you set EC2_ROOT_SSH_KEY in hbase-ec2-env.sh to the local filesystem path where the private key file is located?

Are the permissions correct on the private key file? Try: chmod 600 /path/to/private/key.

If all above fails, change '-q' to '-v -v' in SSH_OPTS in hbase-ec2-env.sh and retry. This will produce a lot of debug output from SSH on the console, which may point to the problem.

When I run:

hbase-ec2 launch-cluster testcluster 3 3

I keep getting 'lost connection' messages (See below).  Tried this 4 times.
Please help.  Thanks.
