Issue Description: Ambari Showing Wrong NIFI Version After Upgrading to HDF 3.3 , as per release notes , the NIFI version in HDF-3.3 is 1.8 but ambari shows it as 1.7 in Stacks and Versions page.

Root cause : This is a known bug in hdf-ambari-mpack-3.3.0.0-165 ( the mpack used by ambari to manage HDF-3.3 ) This issue is fixedin HDF-3.3.1 mpack.

Solution : we can ignore the version shown in the stacks and services as its just ambari shows its wrong. we can verify the NIFI version in nifi ui or from hdf-select command in Host where nifi is installed.

Workaround :

• Navigate to : /var/lib/ambari-server/resources/mpacks/hdf-ambari-mpack-3.3.0.0-165/hdp-addon-services/HDF/3.3/NIFI/1.7.0
• Edit the File : metainfo.xml

Change the line :

<version>1.7.0</version>

to

<version>1.8.0</version>

• Restart ambari server.
