3  安装spark

#解压
tar zxvf  spark-3.5.1-bin-hadoop3.tgz
sudo mv  spark-3.5.1-bin-hadoop3/ /usr/local/spark/
#配置环境变量(slave12,slave13同样配置)
sudo vi /etc/profile
export SPARK_HOME=/usr/local/spark
export PATH=$PATH:$SPARK_HOME/bin
export PATH=$PATH:$SPARK_HOME/sbin
source /etc/profile
#配置环境变量
cd /usr/local/spark/conf/
cp  spark-env.sh.template  spark-env.sh
vim spark-env.sh
export JAVA_HOME=/usr/local/jdk
export SCALA_HOME=/usr/local/scala
export HADOOP_CONF_DIR=/data/hadoop/etc/hadoop/
export SPARK_MASTER_HOST=master11

export SPARK_WORKER_CORES=2
export SPARK_MASTER_PORT=7077
export SPARK_MASTER_WEBUI_PORT=8082
export SPARK_DIST_CLASSPATH=$(/data/hadoop/bin/hadoop classpath)
#修改workers配置文件
cp workers.template workers
vim workers
slave12
slave13
#分发文件到slave12,slave13
scp  -r /usr/local/spark/ slave12:/usr/local/
scp  -r /usr/local/spark/ slave13:/usr/local/
scp  -r /usr/local/scala/ slave12:/usr/local/
scp  -r /usr/local/scala/ slave13:/usr/local/

二 启动

#master11启动
[root@master11 ~]# /usr/local/spark/sbin/start-all.sh

#报错

#解决
cd /usr/local/spark/jars/
wget https://repo1.maven.org/maven2/org/slf4j/slf4j-api/1.7.9/slf4j-api-1.7.9.jar

 三 Spark 与Hive 集成

1 拷贝配置文件和Mysql 驱动

cp /data/hive/conf/hive-site.xml /usr/local/spark/conf/
cp /data/hadoop/etc/hadoop/hdfs-site.xml /usr/local/spark/conf/
cp /data/hadoop/etc/hadoop/core-site.xml /usr/local/spark/conf/
cp /data/hive/lib/mysql-connector-java-8.0.29.jar  /usr/local/spark/jars/

2 登录hive，创建测试表

hive
create  database testdb;
use testdb;
create table test(id int,name string) row format delimited fields terminated by ',';
#创建测试文件
cat /root/test.csv
1,lucy
2,lili
#导入数据
load data local inpath '/root/test.csv' overwrite  into table test;

3 启动 spark-sql

spark-sql  --master spark://master11:7077  --executor-memory 512m  --total-executor-cores 2  --driver-class-path /usr/local/spark/jars/mysql-connector-java-8.0.29.jar
