阿里腾讯云 hadoop+spark集群搭建(2)
linux版本: centos7
hadoop版本: 3.1.1
spark版本: 2.3.2
在1中已经搭建好了hadoop,接下来就是spark。
为方便起见,用shell脚本完成下载spark、hive(后面再搭,先把spark跑起来)的操作。
download_file.sh
-------------------------------
#!/bin/bash
TARGET=files
HADOOP_VERSION=3.1.1
HIVE_VERSION=2.3.3
SPARK_VERSION=2.3.2
HADOOP_FILE=hadoop-$HADOOP_VERSION.tar.gz
HIVE_FILE=apache-hive-$HIVE_VERSION-bin.tar.gz
SPARK_FILE=spark-$SPARK_VERSION-bin-hadoop2.7.tgz
if [ ! -f "$HADOOP_FILE" ]; then
echo "https://www-us.apache.org/dist/hadoop/common/hadoop-$HADOOP_VERSION/$HADOOP_FILE is downloading"
curl -O https://www-us.apache.org/dist/hadoop/common/hadoop-$HADOOP_VERSION/$HADOOP_FILE
fi
echo "Hadoop is completed!"
if [ ! -f "$HIVE_FILE" ]; then
echo "https://www-us.apache.org/dist/hive/hive-$HIVE_VERSION/$HIVE_FILE is downloading"
curl -O https://www-us.apache.org/dist/hive/hive-$HIVE_VERSION/$HIVE_FILE
fi
echo "HIVE is completed!"
if [ ! -f "$SPARK_FILE" ]; then
echo "https://www-us.apache.org/dist/spark/spark-$SPARK_VERSION/$SPARK_FILE is downloading"
curl -O https://www-us.apache.org/dist/spark/spark-$SPARK_VERSION/$SPARK_FILE
fi
echo "$SPARK_FILE completed!"
-
运行脚本下载spark和hive
-
解压缩到~/hadoop下(hadoop用户身份)
$ cd ~/hadoop $ ls hadoop-3.1.1 hive-2.3.3 spark-2.3.2
-
下载Anaconda3
$ cd ~/hadoop $ ls hadoop-3.1.1 hive-2.3.3 spark-2.3.2
由于我打算使用pyspark,且想使用python3,所以安装Anaconda3。
$ curl -O https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-5.3.0-Linux-x86_64.sh $ ./Anaconda3-5.3.0-Linux-x86_64.sh
-
配置文件
- spark-env.sh
追加如下内容
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export JRE_HOME=${JAVA_HOME}/jre export HADOOP_HOME=/home/hadoop/hadoop/hadoop-3.1.1 export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop export SPARK_MASTER_PORT=7077 export SPARK_MASTER_HOST=master
- slaves
slave1 slave2
- log4j.properties
若想日志信息仅记载警告信息,则将
log4j.rootCategory=INFO, console
改为log4j.rootCategory=WARN, console
- /etc/profile.d/spark-2.3.2.sh
export SPARK_HOME=/home/hadoop/hadoop/spark-2.3.2 export PATH=$SPARK_HOME/bin:$PATH
$ source /etc/profile
以上内容master和slaves机器都要进行,master配置好拷贝过去就可以了。
-
master机器运行spark
$ cd $SPARK_HOME/sbin $ ./start-all.sh <!--先执行start-master再执行start-slave--> $ jps 16000 Master 15348 NameNode 15598 SecondaryNameNode 16158 Jps <!--只启动了hdfs和spark-->
打开http://master:8080(公网),显示Alive Workers:2,完成。
