昨天使用hadoop跑五一的数据,发现报错: Container [pid=,containerID=container_1453101066555_4130018_01_000067] GB physical memory used; GB virtual memory used. Killing container. 发现是内存溢出了,遇到这种问题首先要判断是map阶段溢出还是reduce阶段溢出,然后分别设置其内存的大小,比如: 在运行hive sql前加上 : (map) 或者 (red…

当运行mapreduce的时候,有时候会出现异常信息,提示物理内存或者虚拟内存超出限制,默认情况下:虚拟内存是物理内存的2.1倍.异常信息类似如下: Container [pid=13026,containerID=container_1449820132317_0013_01_000012] is running beyond physical memory limits. Current usage: 1.0 GB of 1 GB physical memory used; 1.7 GB o…

单机搭建了2.6.5的伪分布式集群,写了一个tf-idf计算程序,分词用的是结巴分词,使用standalone模式运行没有任何问题,切换到伪分布式模式运行一直报错: hadoop is running beyond virtual memory limits 大概意思就是使用虚拟内存超出了限制. 网上参考了好几篇博客,几乎都是再说更改hadoop-env和mapred-site.xml hadoop-env直接更改堆大小 export HADOOP_HEAPSIZE=1000 mapred-si…

实际遇到的真实问题,解决方法: 1.调整虚拟内存率yarn.nodemanager.vmem-pmem-ratio (这个hadoop默认是2.1) 2.调整map与reduce的在AM中的大小大于yarn里RM可分配的最小值yarn.scheduler.minimum-allocation-mb 大小因为在Container中计算使用的虚拟内存来自 map虚拟内大小=max(yarn.scheduler.minimum-allocation-mb,mapreduce.map.memory.mb…

当运行中出现Container is running beyond physical memory这个问题出现主要是因为物理内存不足导致的,在执行mapreduce的时候,每个map和reduce都有自己分配到内存的最大值,当map函数需要的内存大于这个值就会报这个错误,解决方法: 在mapreduc-site.xml配置里面设置mapreduce的内存分配大小 <property> <name>mapreduce.map.memory.mb</name> <va…
