Karel Vervaeke commented on WHIRR-653:
--------------------------------------
I don't know if you can get the exit code via the API (not saying you can't - I
just don't know), but the scripts leave behind an 'rc' file containing the exit
code.
e.g. /tmp/bootstrap-.../rc
> Script exit codes aren't being checked

> Key: WHIRR-653
> URL: https://issues.apache.org/jira/browse/WHIRR-653
> Project: Whirr
> Issue Type: Bug
> Components: core
> Affects Versions: 0.9.0
> Environment: local: OSX, remote RHEL6.3
> Reporter: Steve Loughran
> Priority: Critical
>
> 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.
