branch 2.2.2 is failing unit test cases

[Amey Jain <a....@gmail.com>]

I cloned and ran mvn clean install on the ambari branch 2.2.2

It runs for around 40 mins and failes at the following test cases.

I have installed as per the developer guide for ambari.
Any issues that I need to take care before i can build Ambari.


Thanks
