     [exec]     -1 javac.  The applied patch generated 64 javac compiler warnings (more than
the trunk's current 124 warnings).

There are no tests for the current EC2 scripts, so I tested this manually by running through
starting a cluster, running a job, and shutting the cluster down. I tested a failure by setting
an invalid key name.

The -1 for javac is odd, since the number went down according to the message, and furthermore
this patch doesn't change any Java code.

> For example, if an ec2-authorize command fails the script should stop so that the problem
is easier to debug.
