[SOLVED] Hadoop MapReduce Unable to connect to ResourceManager

I'm trying to setup Hadoop with a Single Node Cluster (Psuedo-distributed) and using the apache guide to do so. Right now I'm trying to run a MapReduce job and using the example it provides bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-3.0.0-alpha3.jar grep input output 'dfs[a-z]+'

hadoop@hadoop:/usr/local/hadoop$ bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-3.0.0-alpha3.jar grep input output 'dfs[a-z]+'
xxxx-xx-xx xx:xx:xx,xxx INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8032

Looking this issue up online, everyone else that has this problem seem to have it with YARN but not MapReduce. And my hdfs-site.xml is the same as mentioned in the guide:

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

I ran jps although I don't know what I'm looking for here:

hadoop@hadoop:/usr/local/hadoop$ jps
9860 DataNode
10075 SecondaryNameNode
9708 NameNode
11021 Jps

Any help is appreciated.

Edit: I looked into hadoop-hadoop-resourcemanager-hadoop.log and found this:

Edit2: here's my yarn-site.xml if it helps:

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

        <value>JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME</value>
    </property>
</configuration>
