Spark(三): 安装与配置

目录:

  • Spark集群安装
  • 参数配置
  • 测试验证

Spark集群安装:


  • 在ambari -service 界面选择 “add Service",如图:
  • 在弹出界面选中spark服务,如图:

  • "下一步”,分配host节点,因为前期我们已经安装了hadoop 和hbase集群,按向导分配 spark history Server即可
  • 分配client,如下图:
  • 发布安装,如下正确状态

参数配置:


  • 安装完成后,重启hdfs 和 yarn
  • 查看 spark服务,spark thrift server 未正常启动,日志如下:

  •  解决方案:调整yarn相关参数配置 yarn.nodemanager.resource.memory-mb、yarn.scheduler.maximum-allocation-mb

  •  yarn.nodemanager.resource.memory-mb

    表示该节点上YARN可使用的物理内存总量,默认是8192(MB),注意,我本机的hdp2-3内存为4G,默认设置的值是512M,调整为如下图大小

  • yarn.scheduler.maximum-allocation-mb

    单个任务可申请的最多物理内存量,默认是8192(MB)。

  • 保存配置,重启依赖该配置的服务,正常后如下图:

  •  

测试验证:


  • 在任一安装spark client机器(hdp4),将目录切换至 spark 安装目录的 bin目录下
  • 命令: ./spark-sql
  • sql命令: show database;  如下图
  • 查看历史记录,如下:
