Using Cloudera Altus Director 6.3 to deploy CDH 6.3 to AWS.

I submitted a similar post back in April, thinking that it had since been resolved - but apparently not. We are ramping up CDH6 deployments again since our initial testing in April and again are seeing Hue fail to start during first run of CDH6 deployments due to Python lib folders being too restrictive. Interestingly we do not see this issue when using the same CentOS 7.6 based AMI to deploy CDH 5.16.2 clusters. The Python lib permissions differ on between the CDH5 and CDH6 deployments:

CDH5:

ls -l /usr/lib/python2.7/site-packages/six*
-rw-r--r--. 1 root root 29664 Jan 2 2015 /usr/lib/python2.7/site-packages/six.py
-rw-r--r--. 1 root root 29708 Nov 20 2015 /usr/lib/python2.7/site-packages/six.pyc
-rw-r--r--. 1 root root 29708 Nov 20 2015 /usr/lib/python2.7/site-packages/six.pyo

/usr/lib/python2.7/site-packages/six-1.9.0-py2.7.egg-info:

-rw-r--r--. 1 root root 249 Nov 20 2015 SOURCES.txt
-rw-r--r--. 1 root root 4 Nov 20 2015 top_level.txt

CDH6:

ls -l /usr/lib/python2.7/site-packages/six*
-rw-r-----. 1 root root 32452 Aug 15 18:09 /usr/lib/python2.7/site-packages/six.py

Again, we use the same AWS AMI for the CDH5 and 6 deployments. For CDH6 I have to manually fix the permissions on all the nodes prior to first run in order to avoid director declaring the deployment failed. This is really hampering our CDH6 rollout.

We updated our Packer image build to skip the CIS rule for more restrictive umask (referenced above), after which Hue successfully started during cluster firstrun.

Some additional information...

We use Packer to build our images, and apply RedHat's CIS security policy for compliance reasons which sets a more restrictive umask in /etc/bashrc

if [ $UID -gt 199 ] && [ “/usr/bin/id -gn” = “/usr/bin/id -un” ]; then
      umask 027
   else
      umask 022
   fi

I'm thinking this doesn't effect our CDH5 deployments because those images already have the correct package version installed, however during CDH6 bootstrap, updated version are required and are installed using 027 umask resulting in no permissions for non-root user. Does the cluster bootstrap process assume umask 022 for non-root users?
