Review request for Ambari and Alejandro Fernandez.


Bugs: AMBARI-20400
    https://issues.apache.org/jira/browse/AMBARI-20400


Repository: ambari


Description
-------

It's possible to install a cluster without Tez and Slider via blueprint. In 
this case, Yarn historyserver start logic prints two warnings about unable to 
copy tez and slider tar ball to HDFS.
Yarn history server should skip the copy hdfs tar ball logic for tez and slider 
if they are not installed.
