Description

Sentry currently specifies the com.codahale.metrics package, version 3.0.2, in the top level pom.xml. When building Sentry, the Hadoop dependencies specifiy version 3.2.2, which changed the maven repo namespace to io.dropwizard.metrics. This conflict commonly causes test failures and classpath issues.

After reaching out on the mailing list, there appears to be no legitimate reason to be using the outdated (3.0.2) version of metrics, and we should be able to safely bump to io.dropwizard.metrics 3.2.2 to resolve the conflicting dependencies with the greater Hadoop ecosystem.
