[jira] [Commented] (BIGTOP-84) Package removal fails in case alternatives are deleted or damaged

["Roman Shaposhnik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BIGTOP-84?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13099257#comment-13099257 ] 

Roman Shaposhnik commented on BIGTOP-84:
----------------------------------------

I'm inclined to fix this by disregarding the exit code from the alternatives command. Something along the lines of:

alternatives --remove XXXX || true

Please let me know if there are any objections to it

> Quite a few of our packages use alternatives --remove mta in there pre-unistall steps. This works fine for as long as the alternative is there and is not damaged, but prevents package removal in any other case:
> # rpm -e hadoop-hive
> ....
> error: %preun(hadoop-hive-0.7.1+42.4-2.noarch) scriptlet failed, exit status 2
