我无法在Hadoop 3.0.0-cdh6.3.2上运行Hadoop jar

Question

我有一台安装了Hadoop 3.0.0-cdh6.3.2的机器。我运行了这个

hadoop jar helloworld.jar solution.CardDriver /user/vmuser/playing_cards_simple /user/vmuser/output

告诉我这个错误:

我

/etc/hadoop/conf/mapred-site.xml 
/etc/hadoop/conf/core-site.xml

的值

HADOOP_MAPRED_HOME=${/usr/lib/hadoop-mapreduce} . I tried with $HADOOP_HOME but gave a lot of errors.

我没有改变yarn-site.xml (yarn.application.classpath的值被设置，但我不知道是否有正确的。yarn-site.xml的值为:

<description>Classpath for typical applications.</description>
<name>yarn.application.classpath</name>
<value>
$HADOOP_CONF_DIR,
$HADOOP_COMMON_HOME/*,$HADOOP_COMMON_HOME/lib/*,
$HADOOP_HDFS_HOME/*,$HADOOP_HDFS_HOME/lib/*,
$HADOOP_MAPRED_HOME/*,$HADOOP_MAPRED_HOME/lib/*,
$HADOOP_YARN_HOME/*,$HADOOP_YARN_HOME/lib/*
</value>
</property> 

请帮忙我花了好几天时间在这件事上，任何光都可以帮我很多。

Answer 1

这是/etc/hadoop/conf/yarn-site.xml中变量的问题

<property>
<description>Classpath for typical applications.</description>
<name>yarn.application.classpath</name>
<value>
/etc/hadoop/conf,
/usr/lib/hadoop/*,
/usr/lib/hadoop/lib/*,
/usr/lib/hadoop-hdfs/*,
/usr/lib/hadoop-hdfs/lib/*,
/usr/lib/hadoop-mapreduce/*,
/usr/lib/hadoop-mapreduce/lib/*,
/usr/lib/hadoop-yarn/*,
/usr/lib/hadoop-yarn/lib/*
</value>
</property>

你不需要其他任何东西。
