Review request for Ambari and Mahadev Konar.


Bugs: AMBARI-21823
    https://issues.apache.org/jira/browse/AMBARI-21823


Repository: ambari


Description
-------

Scenario:
* Upgrade ambari from Ambari 2.2.2.0 to 2.5.2.0
* Upgrade BI 420 from HDP 2.6.2.0
* 
In this upgrade scenario, Spark1 was upgraded from BI->HDP
Spark2 was added after upgrade.
In this cluster , it has Spark and Spark2 both. 
However, spark2 shuffle is not added to yarn.nodemanager.aux-services.
{code}
 <property>
      <name>yarn.nodemanager.aux-services</name>
      <value>mapreduce_shuffle,spark_shuffle</value>
    </property>{code}

The migration from IOP to HDP is correct - we're setting the Spark1 properties. Looks like when adding Spark2, the stack advisor is not suggestion adding the spark2_shuffle. This goes back to the default behavior of Ambari which is to always add both {{spark_shuffle}} and {{spark2_shuffle}} properties when adding either Spark1 or Spark2. 

This was never an issue previously since we were always adding both aux-services. We can fix this in one of two ways:
- On upgrade, just add both (like we're doing for the 4.2.5 migration)
- Fix stack advisor to correct these properties based on which Spark versions are installed
