-------------------------------------
Summary: After stack_upgrade 2.2 to 2.3 hook script fails due to
missing /configurations/tez-site/tez.am.view-acls value
Key: AMBARI-13835
URL: https://issues.apache.org/jira/browse/AMBARI-13835
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.1.2
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Priority: Critical
Fix For: 2.1.3
After upgrading to 2.1.x hook script fails due to missing
{{/configurations/tez-site/tez.am.view-acls}} value. The following errors may
be seen when executing agent-side scripts (start, stop, etc...):

File
"/usr/lib/python2.6/site-packages/resource_management/libraries/script/config_dictionary.py",
line 81, in __getattr__
raise Fail("Configuration parameter '" + self.name + "' was not found in
configurations dictionary!")
resource_management.core.exceptions.Fail: Configuration parameter
'tez.am.view-acls' was not found in configurations dictionary!

Error: Error: Unable to run the custom hook script ['/usr/bin/python2.7',
'/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py',
'ANY', '/var/lib/ambari-agent/data/command-8752.json',
'/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY',
'/var/lib/ambari-agent/data/structured-out-8752.json', 'INFO',
'/var/lib/ambari-agent/tmp’]
{noformat}
*Cause*
It appears that the cause is from this line:
{code:title=stacks/HDP/2.0.6/hooks/before-ANY/scripts/params.py:220}
tez_am_view_acls = config['configurations']['tez-site']["tez.am.view-acls"]
{code}
Since {{/configurations/tez-site/tez.am.view-acls}} was not set, the python
script failed.
*Solution*
Either protect this call using something like
{code}
default("/configurations/tez-site/tez.am.view-acls", "*")
{code}
Or ensure the value is set during the upgrade process when transitioning to
Ambari 2.1.0.
