-------------------------------
Summary: ExecuteScript in resource_management is broken
Key: AMBARI-23665
URL: https://issues.apache.org/jira/browse/AMBARI-23665
Project: Ambari
Issue Type: Bug
Components: ambari-agent
Affects Versions: 2.6.1
Environment: Ambari 2.6.1.3 is installed as RPM from
[http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.1.3] but
the code in {{trunk}} looks the same:
https://github.com/apache/ambari/blob/trunk/ambari-common/src/main/python/resource_management/core/providers/system.py
Reporter: Kirill
When custom service script contains the following:
{code}
def configure(self, env, upgrade_type=None, config_dir=None):
import params
env.set_params(params)
ExecuteScript(
code=constants.some_string,
interpreter='/usr/bin/env python',
)
{code}
service installation fails with:
{code}
Traceback (most recent call last):

When {{ExecuteScript}} is called like:
{code}
def configure(self, env, upgrade_type=None, config_dir=None):
import params
env.set_params(params)
ExecuteScript('some-text',
code=constants.constants.some_string,
interpreter='/usr/bin/env python',
)
{code}
installation fails with:
