Ambari HDP 2.3 cannot install Ranger

[Chris Buccella]

I'm using the ambari plugin code from git. The image is based on Centos 6.7

When creating a cluster with Ranger enabled, installation of Ranger fails.

ranger-admin-site.xml has bad/missing values for:
- ranger.externalurl
- ranger.jpa.audit.jdbc.url
- ranger.jpa.jdbc.url

After setting these, I was able to successfully run the failed portion of the install:
python /usr/hdp/current/ranger-admin/db_setup.py -javapatch

This is probably rooted in a bug in Ambari. But until that's fixed, Sahara's Ambari plugin can mitigate the problem so that the user can successfully provision a cluster that includes Ranger.

For reference: https://issues.apache.org/jira/browse/AMBARI-12413

we can change mysql to mariadb,like:

/opt/stack/sahara/sahara/plugins/ambary (192)

        sudo("yum install -y mariadb-server")
        sudo("service mariadb start")
mysql and mariadb can replace by each other,this can solve the bug

[Luigi Toscano (ltoscano)]

"yum install mysql-server" on centos 7 should install mariadb-server.
The name of the service is indeed different.

[Vitalii Gridnev (vgridnev)]

That will not solve this bug, the issue is that Ambari can't deploy Ranger via blueprints. See open issue: https://issues.apache.org/jira/browse/AMBARI-12413 . Additionally, database stuff has to be installed separately and will be installed via DIB.
