[MarkLogic Dev General] Getting not an usable net address error when integrating ML 9 with Connector-for-Hadoop2-2.2.3?

[C. Yaswanth]

Following this https://docs.marklogic.com/guide/mapreduce/quickstart I am
running sample marklogic-hello-world.xml by using the configuration that
was present in the documentation. My localhost name is `ubuntu.localdomain`
. When i am giving the same in my configuration file it is throwing error
like this

My configuration file is like this


    <configuration>

            <name>mapreduce.marklogic.input.username</name>
            <value>admin</value>

        <property>

        </property>
        <property>

            <value>admin</value>
        </property>
        <property>

            <value>admin</value>
        </property>
        <property>

        </property>
        <property>

            <value>TEXT</value>
        </property>
    </configuration>


I had tried by giving various names for this
`mapreduce.marklogic.input.host` i tried with `127.0.0.1` & `localhost` but
by default it is taking `ubuntu.localdomain`.

I dont know why it is taking default one rather than taking the one which i
had specified in configuration.xml file (i.e.`127.0.0.1` etc) .

I had used the below command to run this

    hadoop jar \
      $CONNECTOR_HOME/lib/marklogic-mapreduce-examples-version.jar \
      com.marklogic.mapreduce.examples.HelloWorld -libjars $LIBJARS \
      -conf marklogic-hello-world.xml

As specifed in the document.

How can i overcome this ? Any help is appreciated ..

Thanks
