原因分析 CDH 集群环境没有对 Container分配足够的运行环境(内存) 解决办法 需要修改的配置文件,将具体的配置项修改匹配集群环境资源.如下: 配置文件 配置设置 解释 计算值(参考) yarn-site.xml yarn.nodemanager.resource.memory-mb 分配给容器的物理内存数量 = 52 * 2 =104 G yarn-site.xml yarn.scheduler.minimum-allocation-mb 容器可以请求的最小物理内存量(以 MiB 为…

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…

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…
