Steve Loughran updated WHIRR-653:
---------------------------------

    Attachment: whirr-654.txt

This converts error results into exceptions. However it causes problems with the outer classes that want to spin until the script succeeds. Guess what: it isn't going to.

> My installer script bails out with an {{exit 1}} on many operations, such as
> {{chown -R hadoop:hadoop $HADOOP_PID_DIR  || exit 1;}}
> This is to find problems early and so aid debugging of the installation.
> Even when a script fails this way, Whirr declares that the installation was successful. 
> It must check the return codes to be confident that the operation succeeded.
