Description

When I try compiling Hadoop with JDK 8 like this

mvn clean package -Pdist -Dtar -DskipTests -Djavac.version=1.8

I get this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hadoop-yarn-common: Compilation failure: Compilation failure:
