Also, it looks like the following chunk
{code}
    <component name="NODEMANAGER">
      <changes>
        <definition xsi:type="configure" id="hdp_2_6_0_0_enable_mapreduce_shuffle_connection_keepalive">
          <type>mapred-site</type>
          <set key="mapreduce.shuffle.connection-keep-alive.enable" value="true"/>
        </definition>
      </changes>
    </component>
{code}

is inside the service section for *OOZIE*. It should be in *YARN*.

You can include [~ncole@hortonworks.com] and [~jonathan.hurley] to review the upgrade changes.
