> 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...):
> {noformat}
> 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!
> {noformat}
> {noformat}
> 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.
