spark 2.3-hadoop-2.7
1.配置環(huán)境變量
export SPARK_HOME=/opt/spark
export PATH=$PATH:$SPARK/bin
2.修改spark-env.sh
cp /opt/spark-2.3-hadoop-2.7/conf/spark-env.sh.template /opt/spark-2.3-hadoop-2.7/conf/spark-env.sh
在末尾添加
export JAVA_HOME=/opt/jdk-1.8
export SCALA_HOME=/opt/scala-2.11
export HADOOP_HOME=/opt/hadoop-2.7
export HADOOP_CONF_DIR=/opt/hadoop-2.7/etc/hadoop
export SPARK_MASTER_IP=hserver-1
export SPARK_WORKER_MEMORY=1g
export SPARK_WORKER_CORES=1
export SPARK_WORKER_INSTANCES=1
3.修改slaves文件(添加Worker節(jié)點)
cp /opt/spark-2.3-hadoop-2.7/conf/slaves.template cp /opt/spark-2.3-hadoop-2.7/conf/slaves
hserver-2
hserver-3
4.把spark拷貝到另外兩臺機器
scp -r /opt/spark-2.3-hadoop-2.7 root@hserver-2://opt/
scp -r /opt/spark-2.3-hadoop-2.7 root@hserver-3://opt/
5.啟動spark
/opt/spark-2.3-hadoop-2.7/sbin/start-all.sh
