Jingyi Mei commented on MADLIB-1248:
------------------------------------
This issue was caused by not returning 1 right after madpack calling
_append_uninstall_madlib_sqlfile and get return_signal == 1 see code here
([https://github.com/apache/madlib/blob/master/src/madpack/madpack.py#L1075).]
Thus madpack will keep going and calls _append_install_madlib_sqlfile which is
not needed.

> Project: Apache MADlib
> Issue Type: Bug
> Components: Madpack
> Reporter: Orhan Kislal
> Assignee: Jingyi Mei
> Priority: Major
>
> Reinstalling on a database that does not have MADlib already installed fails
> as expected. However, the info messages do not mention this failure. It seems
> the proper error message was lost during the `making madpack operations
> atomic` Jira (MADLIB-1242).
