前置条件
- 已安装好java(选用的是java 1.8.0_191)
- 已安装好scala(选用的是scala 2.11.121)
- 已安装好hadoop(选用的是Hadoop-2.9.2)
- hadoop,hive 版本选择，根据spark默认捆绑hive1.2.1版本，不支持hadoop 3.0 以上的版本，所以选的 Hadoop 是3.0以下的版本，这样不需要重新编译Spark,当然，可以手动编译Spark,这样就可以对Hive,Hadoop,自行选择
安装
- 下载安装包 : spark-2.4.0-bin-hadoop2.7.tgz
- 安装包下载地址: https://archive.apache.org/dist/spark/spark-2.4.0/spark-2.4.0-bin-hadoop2.7.tgz
- 将安装包上传到服务器上进行安装
- 解压压缩包
tar -zxvf spark-2.4.0-bin-hadoop2.7.tgz -C /opt/module/bigdata/
- 配置环境变量(配的是~/.bashrc)
export JAVA_HOME=/opt/module/jdk/jdk1.8.0_191
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export SCALA_HOME=/opt/module/scala/scala-2.11.12
export HADOOP_HOME=/opt/module/bigdata/hadoop-2.9.2
export SPARK_HOME=/opt/module/bigdata/spark-2.4.0-bin-hadoop2.7
export PATH=$JAVA_HOME/bin:$SCALA_HOME/bin:$SPARK_HOME/bin:$SPARK_HOME/sbin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
配置
配置hadoop的classpath
- 下载不带hadoop依赖jar的spark版本
- 需要在spark配置中指定hadoop的classpath
- 配置文件spark-env.sh
### in conf/spark-env.sh ###
# If 'hadoop' binary is on your PATH
export SPARK_DIST_CLASSPATH=$(hadoop classpath)
# With explicit path to 'hadoop' binary
export SPARK_DIST_CLASSPATH=$(/path/to/hadoop/bin/hadoop classpath)
# Passing a Hadoop configuration directory
export SPARK_DIST_CLASSPATH=$(hadoop --config /path/to/configs classpath)
spark-env.sh配置
#!/usr/bin/env bash
