Hadoop 单机搭建 Spark单机搭建

spark下载地址：http://spark.apache.org/downloads.html

spark版本：spark-3.0.0-preview2-bin-hadoop2.7

一、下载并上传解压安装包

tar -xvf spark-3.0.0-preview2-bin-hadoop2.7.tar -C /opt/modules/

二、修改配置文件,配置文件都在安装目录的conf文件夹中

/opt/modules/spark-3.0.0-preview2-bin-hadoop2.7/conf

1、修改spark-env.sh文件

[hadoop@centos01 conf]$ cp spark-env.sh.template spark-env.sh
[hadoop@centos01 conf]$ vi spark-env.sh

export JAVA_HOME=/opt/modules/jdk1.8.0_181
export SPARK_MASTER_IP=centos01
export SPARK_MASTER_PORT=7077

三、启动

sh /opt/modules/spark-3.0.0-preview2-bin-hadoop2.7/sbin/start-master.sh

[hadoop@centos04 conf]$ sh /opt/modules/spark-3.0.0-preview2-bin-hadoop2.7/sbin/start-master.sh
starting org.apache.spark.deploy.master.Master, logging to /opt/modules/spark-3.0.0-preview2-bin-hadoop2.7/logs/spark-hadoop-org.apache.spark.deploy.master.Master-1-centos04.out
[hadoop@centos04 conf]$ 

四、查看节点

[hadoop@centos04 conf]$ jps
10579 Master
11427 Jps
[hadoop@centos04 conf]$ 

五、测试
