Description

Ratis-Metric is depending on the dependency com.github.joshelser:dropwizard-metrics-hadoop-metrics2-reporter: 0.1.2. This in turn depends on the org.apache.hadoop:hadoop-common:2.6.0. This in turn depends on org.apache.hadoop:hadoop-annotations:2.6.0 which have an dependency on a system scoped dependency named jdk.tools:1.6. I'm running java 11 and this dependency doesn't exist in my environment so I can't compile with ratis included in my project because it fails trying to resolve that dependency.

However, the project ratis-hadoop depends on the the dependency org.apache.hadoop:hadoop-common:3.1.1 (which should be upgraded to 3.1.2 because the sources are missing in 3.1.1) which doesn't have the jdk.tools:1.6 dependency. So if I depend on this I can build the project because the faulty 2.6.0 dependency is shadowed transitively by the 3.1.1 dependency and everything is compiling.

The simple fix would be updating so ratis-metric is depending directly on the 3.1.2 dependency instead since it effectively will be the 3.1.1 code you are going run with anyway when running with the ratis-hadoop dependency.
