> 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.
