Spark on Yarn运行错误:Yarn application has already ended! It might have been killed or unable to launch application master

错误原因:在执行任务时检测到虚拟机的内存太小,2.2g的虚拟内存实际值,超过了2.1g的上限,不能满足该任务所需的内存要求,于是Yarn就干掉了执行此任务的contrainer。

解决办法:

在yarn-site.xml文件中加入以下两项配置:

<property>

        <name>yarn.nodemanager.pmem-check-enabled</name>

        <value>false</value>

    </property>

    <property>

        <name>yarn.nodemanager.vmem-check-enabled</name>

        <value>false</value>

    </property>

然后分发到另外两个节点去(分发之前先停掉yarn服务):

scp yarn-site.xml bigdata-pro01.kfk.com:/opt/modules/hadoop-2.6.0/etc/Hadoop

scp yarn-site.xml bigdata-pro03.kfk.com:/opt/modules/hadoop-2.6.0/etc/Hadoop
Spark on Yarn运行错误:Yarn application has already ended! It might have been killed or unable to launch application master

#重新启动yarn和spark
