> The run() function, as defined in dist-layout-stitching.sh and dist-tar-stitching, created
in hadoop-dist/pom.xml, does not properly propagate the error code of a failing command. 
See the following:
> {code}
>     ...
>     "${@}"                 # call fails with non-zero exit code
>     if [ $? != 0 ]; then   
>         echo               
>         echo "Failed!"     
>         echo               
>         exit $?            # $?=result of echo above, likely 0, thus exit with code 0
>     ...
> {code}
