Couple of minor nits below.
can we remove azure maven-checkstyle-plugin definition?
{code}
      <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-checkstyle-plugin</artifactId>
          <configuration>
            <!-- To run with the default Sun ruleset, 
                 comment out the configLocation line -->
            <configLocation>src/config/checkstyle.xml</configLocation>
          </configuration>
          
      </plugin>
{code}

Looks like a few typos
{code:title=hadoop-build-tools/pom.xml}
  <name>Apache Hadoop Build Toolst</name>
{code}

This is the first reference to dependency of hadoop artifact by version. I 
think we are safe without this.
{code:title=pom.xml}
            <dependency>
              <groupId>org.apache.hadoop</groupId>
              <artifactId>hadoop-build-tools</artifactId>
              <version>3.0.0-SNAPSHOT</version>
            </dependency>
{code}

the mvn checkstyle:checkstyle goal fails to the checkstyle/checkstyle.xml file 
being in the incorrect location
{code:title=pom.xml}
          <configuration>
            <configLocation>checkstyle/checkstyle.xml</configLocation>
            <failOnViolation>false</failOnViolation>
            <format>xml</format>
            <format>html</format>
            
<outputFile>${project.build.directory}/test/checkstyle-errors.xml</outputFile>
           </configuration>
{code}
