Description

Found via HDFS-13952.

Reproducible on Maven 3.3.3, but not a problem for Maven 3.5.0 and above.
I had to make the following change in order to compile. Looks like a problem after the ABFS merge.

diff --git a/hadoop-project/pom.xml b/hadoop-project/pom.xml
index cd38376..4c2c267 100644
--- a/hadoop-project/pom.xml

+            </additionalOptions>
           </configuration>
         </plugin>
         <plugin>

Otherwise it gives me this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:3.0.1:jar (module-javadocs) on project hadoop-project: Unable to parse configuration of mojo org.apache.maven.plugins:maven-javadoc-plugin:3.0.1:jar for parameter additionalOptions: Cannot assign configuration entry 'additionalOptions' with value '-Xmaxwarns 10000' of type java.lang.String to property of type java.lang.String[] -> [Help 1]
