-----------------------------------
Resolution: Fixed
> RPM: Upgrade does not work from 1.15 to 1.15.1
> ----------------------------------------------
>
> Key: MADLIB-1278
> URL: https://issues.apache.org/jira/browse/MADLIB-1278
> Project: Apache MADlib
> Issue Type: Bug
> Components: Build System
> Reporter: Orhan Kislal
> Priority: Major
> Fix For: v1.15.1
>
>
> It seems there is an issue with upgrading the 1.15 version of MADlib rpm. The
> RPM upgrade process works as follows:
> {code}
> Run the %pre section of the RPM being installed.
> Install the files that the RPM provides.
> Run the %post section of the RPM.
> Run the %preun of the old package.
> Delete any old files not overwritten by the newer version. ...
> Run the %postun hook of the old package.
> {code}
> In version 1.15, we added a post-uninstall script that removed the links for
> Current, bin and doc folders (also cleaned the Versions folder if empty).
> While this makes sense for uninstallation, upgrade process runs this script
> at the end and removes the newly updated links.
> We should provide a script to recreate these links with the release of 1.15.1
> and any other release that supports upgrading from 1.15.
