Services won't restart after upgrading Ambari to 2.4.0.1

Hello

We've upgraded Ambari from 2.1.2.1 to 2.4.0.1 according to the the upgrade guide http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-upgrade/content/ambari_upgrade_guide.html

The entire process was successful and was performed according to the guide.

After starting the Ambari i'm able to login and there is a restart indicator near every service (according to point 14 in the guide) http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-upgrade/content/upgrade_ambari.html

However - the services won't start \ restart at all. Every service fails with the same error: resource_management.core.exceptions.Fail: Execution of 'ambari-python-wrap /usr/bin/conf-select set-conf-dir --package hadoop --stack-version 2.3.2.0-2950 --conf-version 0' returned 1. /usr/hdp/2.3.2.0-2950/hadoop/conf does not exist

Error: Error: Unable to run the custom hook script ['/usr/bin/python', '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py', 'ANY', '/var/lib/ambari-agent/data/command-2602.json', '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY', '/var/lib/ambari-agent/data/structured-out-2602.json', 'INFO', '/var/lib/ambari-agent/tmp']

Any ideas ?

Is this a known bug i missed ??

@Adi Jabkowsky

Do you have a symlink inside the "/usr/hdp/2.3.2.0-2950/hadoop/" directory with name "conf" pointing to "/etc/hadoop/2.3.2.0-2950/0" ?

If not then can you create a symlink inside the "/usr/hdp/2.3.2.0-2950/hadoop/" pointing to it like following and then try again:

lrwxrwxrwx.  1 root root        12 Sep 18 06:33 conf -> /etc/hadoop/2.3.2.0-2950/0
