Hadoop - DataNode and Namenode not starting

Question

I installed Hadoop on Ubuntu but when I run ./start-all.sh script in sbin folder the DataNode and Namenode not starting. I got the following settings in the config files:

core-site.xml

<configuration>
    <property>
        <name>dfs.default.FS</name>
        <value>hdfs://localhost:50071</value>
    </property>

    <property>
        <name>dhadoop.tmp.dir</name>
        <value>usr/local/hadoop</value>
    </property>
</configuration>

hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>

mapred-site.xml

<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
</configuration>

yarn-site.xml

<configuration>
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce-shuffle</value>
    </property>

    <property>
        <name>yarn.nodemanager.aux-services.shuffle.class</name>
        <value>org.apache.hadoop.ShuffleHandler</value>
    </property>
</configuration>

Could you please help me do I need to add any other information in the xml files? I have no idea what is wrong here?

By the way `dhadoop.tmp.dir` has a d at the beginning of it. And the mapred & yarn site aren't needed for the namenode / datanode, so you may want to ignore them. Try running `start-dfs` script instead — OneCricketeer, Nov 03 '17 at 12:41
