Hadoop運行程序的時候出現如下的錯誤：
17/07/13 15:56:02 INFO mapreduce.Job: Task Id : attempt_1499929582056_0007_m_000000_1, Status : FAILED
Exception from container-launch.

通過網上查詢發現需要在yarn-site.xml中添加
如下配置
<property>
<name>yarn.application.classpath</name>
<value>
/opt/hadoop-2.6.1/etc/*,
/opt/hadoop-2.6.1/etc/hadoop/*,
/opt/hadoop-2.6.1/lib/*,
/opt/hadoop-2.6.1/share/hadoop/common/*,
/opt/hadoop-2.6.1/share/hadoop/common/lib/*,
/opt/hadoop-2.6.1/share/hadoop/mapreduce/*,
/opt/hadoop-2.6.1/share/hadoop/mapreduce/lib/*,
/opt/hadoop-2.6.1/share/hadoop/hdfs/*,
/opt/hadoop-2.6.1/share/hadoop/hdfs/lib/*,
/opt/hadoop-2.6.1/share/hadoop/yarn/*,
/opt/hadoop-2.6.1/share/hadoop/yarn/lib/*
</value>
</property>
然後重新啓動hadoop集羣即可
