> Ubuntu does not use bash as its default shell; as a result bigtop-packages/src/common/hadoop/do-component-build gets executed by dash which does not correctly evaluate:
> [...]
>     if [[ $AUTOCONF_VERSION > 2.60 ]]; then
>         DO_AUTORECONF="create-c++-configure"
>     fi
> fi
> This generates a fleeting error message during the build process.
> Switching the call to this script in bigtop-packages/src/deb/hadoop/rules to use bash instead of sh to execute this script resolves the issue (I will work on a patch).
> However the do-component-build script itself uses #!/bin/sh which is not really correct either - it might make sense to change this and execute this script directly through debian/rules rather than force execution with bash - opinions invited.
