Looks like we're having problems kerberizing after we merged the Solr feature branch. . I will run this up now and validate your fix. Good find @MohanDV !

+1 I ran this up in the CentOS development environment and went through the kerberization process. Before and after kerberization, alerts were visible and the service check passed.
