WARNING: Removed misconfigured rule: OldHadoopPackageImport cause: Missing xPath expression

Make sure your rule definition includes the property element and the value element inside it. For example:

    <rule name="OldHadoopPackageImport"
          message="Avoid importing old Hadoop mapred package, use mapreduce package instead"
          language="java"
          class="net.sourceforge.pmd.lang.rule.XPathRule">
        <properties>
            <property name="xpath" description="XPath expression">
                <value>
                    //ImportDeclaration[Name[contains(@Image, 'org.apache.hadoop.mapred')]]
                </value>
            </property>
        </properties>
    </rule>
