Unable to remove older installations after upgrade to HDP 3.0.1

[#1]

I've tried the procedure on this page:

https://community.hortonworks.com/articles/202904/how-to-remove-all-previous-version-hdp-directories...

on a freshly upgraded HDP setup (version 3.0.1). But when I launch the request it immediately errors out with this in the output:

stdout:

A quick google did not return anything usefull. But it looks like the some of the supporting code for this is missing or we are missing a extra library somewhere?

Hi @Tim Verhoeven,

Removing old stacks and versions is something i personally wont suggest you because at any point you want to downgrade your HDP you might need it. But as you facing the above error i would like to see if below changes help you or not :

I was facing the same issue and changing the below line helped me get past the abouve expection :

Steps

1) go to each ambari agents

[root@asn1 current]#vi /var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py

2) go to line : 77

edit the line from :

all_installed_packages = self.pkg_provider.all_installed_packages()

to

all_installed_packages = self.pkg_provider.installed_packages()

retry the operation via curl again

curl 'http://asn1.openstacklocal:8080/api/v1/clusters/asnaik/requests' -u admin:admin -H "X-Requested-By: ambari" -X POST -d'{"RequestInfo":{"context":"remove_previous_stacks", "action" : "remove_previous_stacks", "parameters" : {"version":"3.0.1.1-84"}}, "Requests/resource_filters": [{"hosts":"asn1.openstacklocal"}]}'

The operation has to be success in UI.

I have created an article in this regard : https://community.hortonworks.com/articles/230893/remove-old-stack-versions-script-doesnt-work-in-am...
