      <title>Required Parquet Jar Files</title>
      <body>
-        <p>Support for the Parquet file format requires these jar files:<sl>
-            <sli>parquet-hadoop-1.7.0.jar</sli>
-            <sli>parquet-common-1.7.0.jar</sli>

+        <p>The <codeph>gphdfs</codeph> protocol supports Parquet versions 1.7.0 and later. For each
+          version, the required Parquet jar files are included in a bundled jar file
+              <codeph>parquet-hadoop-bundle-&lt;<varname>version</varname>>.jar</codeph>. </p>
+        <p>Earlier Parquet versions not use the Java class names <codeph>org.apache.parquet</codeph>
+          and are not supported. The <codeph>gphdfs</codeph> protocol expects the Parquet Java class
+          names to be <codeph>org.apache.parquet.<varname>xxx</varname></codeph>.</p>
        <note>The Cloudera 5.4.x Hadoop distribution includes some Parquet jar files. However, the
          Java class names in the jar files are <codeph>parquet.<varname>xxx</varname></codeph>. The
-            <codeph>gphdfs</codeph> protocol uses the Java class names
-              <codeph>org.apache.parquet.<varname>xxx</varname></codeph>. The jar files with the
-          class name <codeph>org.apache.parquet</codeph> can be downloaded and installed on the
-          Greenplum Database hosts. </note>
-        <p>The <codeph>gphdfs</codeph> protocol also supports using
-            <codeph>parquet-hadoop-bundle-1.7.0.jar</codeph> that contains the classes required to
-          use Parquet within a Hadoop environment. These versions of
-            <codeph>parquet-hadoop-bundle</codeph> are not supported:<ul id="ul_e1z_4xr_zt">
-            <li>Version 1.6 and earlier. The versions do not use the Java class names
-                <codeph>org.apache.parquet</codeph></li>
-            <li>Version 1.8 and later. The versions contain the class <codeph>VersionParser</codeph>
-              that is not supported by <codeph>gphdfs</codeph>.</li>
-          </ul></p>
