在yarn-site.xml 配置文件中增加: <property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> 重启就ok了 这个问题其实是由于 yarn.nodemanager.aux-services 配置错误或者没有配置,其实,如果没有配置这个参数应该会有默认值…

组件:cdh5.14.0 spark是自己编译的spark2.1.0-cdh5.14.0 第一步:确认spark-defaults.conf中添加了如下配置: spark.shuffle.service.enabled true //启用External shuffle Service服务 spark.shuffle.service.port //Shuffle Service服务端口,必须和yarn-site中的一致 spark.dynamicAllocation.enabled true /…

这个是Flink 1.11.1  使用yarn-session 出现的错误:原因是在Flink1.11 之后不再提供flink-shaded-hadoop-*” jars 需要在yarn-session.sh 文件中添加 或者在环境变量中添加 export HADOOP_CLASSPATH=`hadoop classpath` 所以要仔细阅读官网信息,基本上好多东西根据官网来,都能解决…

从2012年8月开始Apache Hadoop YARN(YARN = Yet Another Resource Negotiator)成了Apache Hadoop的一项子工程.自此Apache Hadoop由下面四个子工程组成: Hadoop Comon:核心库,为其他部分服务 Hadoop HDFS:分布式存储系统 Hadoop MapReduce:MapReduce模型的开源实现 Hadoop YARN:新一代Hadoop数据处理框架 概括来说,Hadoop YARN的目的是使得Hado…

spark支持YARN做资源调度器,所以YARN的原理还是应该知道的:http://www.socc2013.org/home/program/a5-vavilapalli.pdf    但总体来说,这是一篇写得一般的论文,它的原理没有什么特别突出的,而且它列举的数据没有对比性,几乎看不出YARN有什么优势.反正我看完的感觉是,YARN的资源分配在延迟上估计很糟糕.而实际使用似乎也印证了这个预感. Abstract  two key shortcomings: 1) tight coupling…
