Apparently Spark and Spark2 work better if they share the same Kerberos 
identity. Since Ambari does not handle the same principal name in multiple 
keytab files, both services need to use the same keytab file - which is 
preferred since Ambari has to do less work.

dropping the previous approach, let's use the same keytab file in both cases


Bugs: AMBARI-20140
https://issues.apache.org/jira/browse/AMBARI-20140


Repository: ambari


Description (updated)
---

Spark2 and Spark1 shares the same principal name. This casuses a problem when 
adding Spark2 to a kerberized cluster with Spark1. Ambari doesn't publish the 
keytab to Spark2 because it thinks it already exists.

We don't cache keytab files that belong to servie principals. The error should 
be added only if the principal is a non service principal (cache should have 
been existed) but there is no cached keytab file

Review request for Ambari, Attila Doroszlai, Balázs Bence Sári, Robert Levas, 
and Sebastian Toader.


Bugs: AMBARI-20140
https://issues.apache.org/jira/browse/AMBARI-20140


Repository: ambari


Description
---

Spark2 and Spark1 shares the same principal name. This casuses a problem when 
adding Spark2 to a kerberized cluster with Spark1. Ambari doesn't publish the 
keytab to Spark2 because it thinks it already exists.

I extended the existing conditional to take the existence of the destination 
keytab file into consideration.

Testing

- Created a cluster with Spark
- Enabled Kerberos
- Added Spark2
- Checked if Spark2 started successfully and the exitence of 
/etc/security/keytabs/spark2.headless.keytab


Existing tests ran without failure.
