按照我的步骤走，这些问题都能解决，我使用的IDE是eclipse

1：复制Hadoop的4个配置文件放到src目录下面：core-site.xml,hdfs-site.xml,log4j.properties,mapred-site.xml,yarn-site.xml

2:配置mapred-site.xml

<configuration>    <property>        <name>mapreduce.framework.name</name>        <value>yarn</value>    </property>    <property>        <name>mapred.remote.os</name>        <value>Linux</value>    </property>    <property>        <name>mapreduce.app-submission.cross-platform</name>        <value>true</value>    </property>    <property>    <name>mapreduce.application.classpath</name>    <value>        /opt/hadoop-2.6.0/etc/hadoop,        /opt/hadoop-2.6.0/share/hadoop/common/*,        /opt/hadoop-2.6.0/share/hadoop/common/lib/*,        /opt/hadoop-2.6.0/share/hadoop/hdfs/*,        /opt/hadoop-2.6.0/share/hadoop/hdfs/lib/*,        /opt/hadoop-2.6.0/share/hadoop/mapreduce/*,        /opt/hadoop-2.6.0/share/hadoop/mapreduce/lib/*,        /opt/hadoop-2.6.0/share/hadoop/yarn/*,        /opt/hadoop-2.6.0/share/hadoop/yarn/lib/*    </value></property>        <property>        <name>mapreduce.jobhistory.address</name>        <value>master:10020</value>    </property>       <property>                <name>mapreduce.jobhistory.webapp.address</name>                <value>master:19888</value>        </property></configuration>

注意mapreduce.application.classpath一定是绝对路径，不要搞什么$HADOOP_HOME,我这里反正是报错的

3：修改yarn-site.xml

<configuration><!-- Site specific YARN configuration properties -->  <property>        <name>yarn.nodemanager.aux-services</name>        <value>mapreduce_shuffle</value>    </property>    <property>        <name>yarn.resourcemanager.address</name>        <value>master:8032</value>    </property><property>    <name>yarn.application.classpath</name>    <value>        /opt/hadoop-2.6.0/etc/hadoop,        /opt/hadoop-2.6.0/share/hadoop/common/*,        /opt/hadoop-2.6.0/share/hadoop/common/lib/*,        /opt/hadoop-2.6.0/share/hadoop/hdfs/*,        /opt/hadoop-2.6.0/share/hadoop/hdfs/lib/*,        /opt/hadoop-2.6.0/share/hadoop/mapreduce/*,        /opt/hadoop-2.6.0/share/hadoop/mapreduce/lib/*,        /opt/hadoop-2.6.0/share/hadoop/yarn/*,        /opt/hadoop-2.6.0/share/hadoop/yarn/lib/*    </value>  </property></configuration>

注意yarn.application.classpath一定是绝对路径，不要搞什么$HADOOP_HOME
