Jonathan Hurley commented on AMBARI-13229:
------------------------------------------
This commit caused failures during RU because we were running the hdp-select
script through the ambari-python-wrap:
{code}
resource_management.core.exceptions.Fail: Execution of 'ambari-python-wrap
hdp-select set zookeeper-server 2.3.0.0-2545' returned 2. /usr/bin/python2.6:
can't open file 'hdp-select': [Errno 2] No such file or directory
{code}
Reverting for now...
> When non-supported version of python is set as default, Ambari fails in
> multiple places

> URL: https://issues.apache.org/jira/browse/AMBARI-13229
> Project: Ambari
> Issue Type: Bug
> Reporter: Andrew Onischuk
> Assignee: Andrew Onischuk
> Fix For: 2.2.0
>
>
> We had an issue where the root user's ~/.bashrc file had Python 3 in the PATH.
> We blindly tried to execute tasks and hdp-select blew up with a syntax issue.
> The vast majority of our tasks will fail with python 3 and as users start to
> more heavily adopt newer version of python for data science tasks there is
> risk that they will leak into being used by our user accounts, specifically
> root for root agents, and the non-root user for non-root agents.
> I would propose that we check the version of python before attempting to start
> the ambari-agent, and fail with a non-zero exit code if we detect a non-
> compliant version.
