Spark+Scala安装

集群环境

hostname	IP
master	192.168.63.12
slave1	192.168.63.13
slave2	192.168.63.14

Scala安装

master

下载scala包

wget https://downloads.lightbend.com/scala/2.11.4/scala-2.11.4.tgz

解压至指定路径

tar -zxvf scala-2.11.4.tgz -C /usr/local/src

设置scala环境变量

vim ~/.bashrc
export SCALA_HOME=/usr/local/src/scala-2.11.4
export PATH=$PATH:$SCALA_HOME/bin

source ~/.bashrc使文件生效

验证

scala分发给其他节点(slave1、slave2)

scp -r /usr/local/src/scala-2.11.4 root@slave1:/usr/local/src
scp -r /usr/local/src/scala-2.11.4 root@slave2:/usr/local/src

master、slave1、slave2

修改~/.bashrc文件

export SCALA_HOME=/usr/local/src/scala-2.11.4
export PATH=$PATH:$SCALA_HOME/bin
source ~/.bashrc

Spark安装

下载spark源码包

wget https://archive.apache.org/dist/spark/spark-2.0.2/spark-2.0.2-bin-hadoop2.6.tgz

解压至指定路径

tar -zxvf spark-2.0.2-bin-hadoop2.6.tgz -C /usr/local/src/

切换到${SPARK_HOME}/conf

修改spark配置文件

vim spark-env.sh

export SCALA_HOME=/usr/local/src/scala-2.11.4
export JAVA_HOME=/usr/local/src/jdk1.8.0_181
export HADOOP_HOME=/usr/local/src/hadoop-2.6.1
export HADOOP_CONF_DIR=/usr/local/src/hadoop-2.6.1/etc/hadoop
SPARK_MASTER_IP=master
SPARK_LOCAL_DIRS=/usr/local/src/spark-2.0.2-bin-hadoop2.6
SPARK_DRIVER_MEMORY=1G

vim slaves

slave1
slave2

spark分发到slave1和slave2节点上

scp -r /usr/local/src/spark-2.0.2-bin-hadoop2.6 root@slave1:/usr/local/src
scp -r /usr/local/src/spark-2.0.2-bin-hadoop2.6 root@slave2:/usr/local/src

master、slave1、slave2

配置spark环境变量

vim ~/.bashrc

export SPARK_HOME=/usr/local/src/spark-2.0.2-bin-hadoop2.6
export PATH=$PATH:$SPARK_HOME/bin

启动集群

cd /usr/local/src/spark-2.0.2-bin-hadoop2.6
./sbin/start-all.sh

查看jps进程

master

slave1

slave2

网页监控面板

master:8080

验证

本地模式

./bin/run-example SparkPi 10 --master local[2]

独立集群Standlone

./bin/spark-submit --class org.apache.spark.examples.SparkPi --master spark://master:7077 examples/jars/spark-examples_2.11-2.0.2.jar 10

集群

spark on yarn

./bin/spark-submit --class org.apache.spark.examples.SparkPi --master yarn-cluster examples/jars/spark-examples_2.11-2.0.2.jar 10
