Colin Patrick McCabe commented on SENTRY-1319:
----------------------------------------------

Thanks, [~rahul9269].  Looks like a good start!

{code}
private final Boolean isHA;
private Boolean isActive;
{code}
Why are these boxed (i.e. {{Boolean}}) rather than just {{boolean}}?

{code}
1726      /* SENTRY-1319 */
1727      @Test
1728      public void testSentryServiceGauges() throws Throwable {
1729        String dbName = "db1";
{code}
I don't think we need a comment with the JIRA name.  People can use git-blame 
to find out which JIRA added these metrics.

I also don't think this should be in {{TestHDFSIntegration.java}} since it 
doesn't have to do with testing the HDFS integration.  Perhaps we should create 
a new JUnit test file?
