Description

When prepare for branch-3.2.2 release, i found there is one issue while create release. And it also exist in trunk.
command line: mvn install site site:stage -DskipTests -DskipShade -Pdist,src -Preleasedocs,docs
failed log show as the following:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.6:site (default-site) on project hadoop-common: failed to get report for org.apache.maven.plugins:maven-dependency-plugin: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hadoop-common: Compilation failure
[ERROR] /Users/hexiaoqiao/Source/hadoop-common/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/metrics2/impl/MetricsSystemImpl.java:[298,5] method <T>register(java.lang.String,java.lang.String,T) is already defined in class org.apache.hadoop.metrics2.impl.MetricsSystemImpl

I am not sure why source code of class MetricsSystemImpl will be changed while building, I try to revert HADOOP-17081 everything seems OK.
