以前一直用的0.20的map reduce框架,今天配置一下yarn,很久不写 BO-KE 了,来一篇吧,把几个主要配置文件贴出来,配置修改后,运行wordcount和自己的测试job全ok,
core-site.xml:
hdfs-site.xml:
mapred-site.xml:
yarn-site.xml: 文件里所有yarn都必须小写,否则相应的端口信息找不到,会在默认端口上启动进程
通过netstat可以看见相应端口已经启动
运行wordcount以及自己写的mapreduce可以成功完成!
另外jobhistory 不是随着hdfs和yarn的启动自动启动,而是需要手动启动,曾经为这个纳闷了好几天,
启动jobhistory进程:
$HADOOP_HOME/sbin/mr-jobhistory-daemon.sh start/stop historyserver
