12일째인 오늘은 Spark를 설치하겠습니다.
목차
1. Spark 설치
1.3 Spark conf 파일 생성 및 수정
2. pyspark 실행
3. Spark 에러
1. Spark 설치
[hadoop@client ~]$ sudo wget https://dlcdn.apache.org/spark/spark-3.2.3/spark-3.2.3-bin-hadoop3.2.tgz
1.1 압축 풀기
[hadoop@client ~]$ tar xvf spark-3.2.3-bin-hadoop3.2.tgz
1.2 이름변경
[hadoop@client ~]$ mv spark-3.2.3-bin-hadoop3.2 spark
[hadoop@client ~]$ ls
1.3 Spark conf 파일 생성 및 수정
slaves, spark-defaults.conf, spark-env.sh 파일 생성
1.3.1 Slaves
[hadoop@client spark]$ cd /home/hadoop/spark/conf
[hadoop@client conf]$ vi slaves
datanode1
datanode2
datanode3
1.3.2 spark-defaults.conf
[hadoop@client conf]$ cp spark-defaults.conf.template spark-defaults.conf
별도의 수정 X
1.3.3 spark-env.sh
[hadoop@client conf]$ cp spark-env.sh.template spark-env.sh
[hadoop@client conf]$ vi spark-env.sh 맨 아래에 추가
export HADOOP_CONF_DIR=/home/hadoop/hadoop/etc/Hadoop
export YARN_CONF_DIR=/home/hadoop/hadoop/etc/hadoop
export SPARK_DRIVER_MEMORY=1024m
export SPARK_EXECUTOR_INSTANCES=1
export SPARK_EXECUTOR_CORES=1
export SPARK_EXECUTOR_MEMORY=1024m
export SPARK_WORKER_DIR=/data/spwork
export SPARK_PID_DIR=/data/sptmp
1.4 환경설정
[hadoop@client ~]$ vi ~/.bashrc
export SPARK_HOME=/home/hadoop/spark
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$SPARK_HOME/bin
Esc -> wq
[hadoop@client ~]$ source ~/.bashrc
[hadoop@client ~]$ echo $SPARK_HOME
2. pyspark 실행
[hadoop@client ~]$ pyspark
