运行简单的样例程序报错

bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.2.jar grep input output 'dfs[a-z.]+'

现象是job卡住, 进度一直停在20%

采用如下解决办法 25后面3个0 可以跑到73%才挂, 然后25后面4个0 跑到100%才挂

#RM(yarn-site.xml) 内存资源配置——两个参数:它们表示单个容器可以申请的最小与最大内存。
<property>
	<name>yarn.scheduler.minimum-allocation-mb</name>
	<value>1024</value>
</property>
<property>
	<name>yarn.scheduler.maximum-allocation-mb</name>
	<value>250000</value>
</property>
 
#NM(yarn-site.xml)前者表示单个节点可用的最大内存,RM中的两个值都不应该超过该值。
后者表示虚拟内存率,即占task所用内存的百分比,默认为2.1.
<property>
	<name>yarn.nodemanager.resource.memory-mb</name>
	<value>250000</value>
</property>
<property>
	<name>yarn.nodemanager.vmem-pmem-ratio</name>
	<value>2.1</value>
</property>
 

找到问题描述: [YARN-4459] container-executor should only kill process groups - ASF JIRA

由于我用的是hadoop 2.7.2版本,  升级到 2.7.3版本尝试一下 

 

换成2.7.3重新部署,果然没有任何问题了.
