Hadoop 系列YARN:资源调度平台(YARN参数解读与调优)

       如果节点有4核8G内存1块硬盘,该节点同时安装HBase,通过下面命令即可获得优化参数

 

[root@nb0 scripts]# python yarn-utils.py -c 4 -m 8 -d 1 -k True Using cores=4 memory=8GB disks=1 hbase=True Profile: cores=4 memory=5120MB reserved=3GB usableMem=5GB disks=1 Num Container=3 Container Ram=1536MB Used Ram=4GB Unused Ram=3GB yarn.scheduler.minimum-allocation-mb=1536 yarn.scheduler.maximum-allocation-mb=4608 yarn.nodemanager.resource.memory-mb=4608 mapreduce.map.memory.mb=1536 mapreduce.map.java.opts=-Xmx1228m mapreduce.reduce.memory.mb=3072 mapreduce.reduce.java.opts=-Xmx2457m yarn.app.mapreduce.am.resource.mb=3072 yarn.app.mapreduce.am.command-opts=-Xmx2457m mapreduce.task.io.sort.mb=614

选项说明

选项

描述

-c

每一个客户机的核数目

-m

每一个客户机拥有的内存总数

-d

每一个客户机拥有的磁盘数目

-k

如果Hbase安装了为”True”,否则为”False”
