--------------------------------------

             Summary: Apache Sentry should depend on the same version of 
metrics-core as hadoop
                 Key: SENTRY-1111
                 URL: https://issues.apache.org/jira/browse/SENTRY-1111
             Project: Sentry
          Issue Type: Bug
          Components: Build
    Affects Versions: 1.6.0
            Reporter: Bhooshan Mogal


Currently, Sentry uses metrics version 3.1.0. However, hadoop trunk still uses 
version 3.0.1 - 
https://github.com/apache/hadoop/blob/trunk/hadoop-project/pom.xml#L891. This 
can cause errors like the following when you try to start sentry because of 
multiple versions of metrics-core in the HADOOP_CLASSPATH.

I am able to reproduce this on a single node cluster running hadoop version 
2.6.0-cdh5.5.2 and Sentry built off of master (or branch-1.6.0). The metrics 
dependencies are required for the sentry-provider-db module. The same should 
apply for other metrics libraries from io.dropwizard.metrics.

Please let me know if you'd like me to work on a patch.
