h5. Steps to reproduce:
* On installer wizard, make install phase fail by killing any install task of 
master component.
* Go back and change hdfs username to hdfs1.
* Proceed ahead and installer wizard completes successfully.
* HDFS service is red.
* Nagios shows no alerts, but API returns INSTALLED status for all hdfs host 
components.
* UI impact: On starting HDFS, all tasks completes successfully with 100% green 
progress bar but service status always remains red.
* Restarting agent resolves the issue.

Looks like AmbariConfig.servicesToPidNames is not getting updated when username 
is changed.
