spark2.4.0完全分布式环境搭建
下载安装包
http://spark.apache.org/downloads.html
解压安装包
tar zxf spark--bin-hadoop2..tgz -C /usr/hdp/
环境配置
# SET SPARK_HOME export SPARK_HOME=/usr/hdp/spark--bin-hadoop2. export PATH=$PATH:$SPARK_HOME/bin
配置文件修改
备注：一下文件都在spark安装的conf文件目录下
文件spark-env.sh
cp spark-env.sh.template spark-env.sh
然后修改spark-env.sh，修改的内容如下：
#!/usr/bin/env bash

# Options read in YARN client/cluster mode
# - SPARK_CONF_DIR, Alternate conf dir. (Default: ${SPARK_HOME}/conf)
# - HADOOP_CONF_DIR, to point Spark towards Hadoop configuration files
# - YARN_CONF_DIR, to point Spark towards YARN configuration files when you use YARN

# - SPARK_EXECUTOR_MEMORY, Memory per Executor (e.g. 1000M, 2G) (Default: 1G)
# - SPARK_DRIVER_MEMORY, Memory for Driver (e.g. 1000M, 2G) (Default: 1G)
# Options for the daemons used in the standalone deploy mode
# - SPARK_MASTER_HOST, to bind the master to a different IP address or hostname
# - SPARK_MASTER_PORT / SPARK_MASTER_WEBUI_PORT, to use non-default ports for the master
# - SPARK_MASTER_OPTS, to set config properties only for the master (e.g. "-Dx=y")
# - SPARK_WORKER_CORES, to set the number of cores to use on this machine
# - SPARK_WORKER_MEMORY, to set how much total memory workers have to give executors (e.g. 1000m, 2g)

文件slaves
cp slaves.template slaves
然后编辑slaves文件，添加的内容如下：
hadoop1 hadoop2 hadoop3
文件的复制
将spark整个的目录复制到另外两个节点上面。
scp -r spark--bin-hadoop2./ root@192.168.217.202:/usr/hdp/ scp -r spark--bin-hadoop2./ root@192.168.217.203:/usr/hdp
文件复制之后，在其他的两个节点上面添加spark的环境变量，同时，修改spark-env.sh文件，将export SPARK_LOCAL_IP=192.168.217.201的IP修改为该节点的IP地址。
集群启动
启动hadoop整个的集群，然后进入到spark的sbin目录下，执行start-all.sh脚本。
[root@hadoop1 hdp]# jps NameNode ResourceManager SecondaryNameNode Master Jps Worker [root@hadoop2 conf]# jps Jps DataNode Worker NodeManager [root@hadoop3 ~]# jps DataNode Jps Worker NodeManager
