Spark3

Apache Spark 是一个开源的大数据处理框架，旨在快速处理大规模数据集。它提供了分布式计算能力，支持批处理和流处理。Spark 提供了丰富的API，支持多种编程语言（如Java、Scala、Python、R），并且能在不同的集群管理器（如Hadoop YARN、Kubernetes）上运行。Spark 通过内存计算和高度优化的执行引擎，显著提高了数据处理速度，广泛应用于数据分析、机器学习和图计算等领域。

基础配置

下载软件包

wget https://dlcdn.apache.org/spark/spark-3.5.4/spark-3.5.4-bin-hadoop3.tgz

解压软件包

tar -zxvf spark-3.5.4-bin-hadoop3.tgz -C /usr/local/software/
ln -s /usr/local/software/spark-3.5.4-bin-hadoop3 /usr/local/software/spark

配置环境变量

cat >> ~/.bash_profile <<"EOF"
## SPARK_HOME
export SPARK_HOME=/usr/local/software/spark
export PATH=$PATH:$SPARK_HOME/bin
EOF
source ~/.bash_profile

查看版本

spark-shell --version

Spark Standalone（单机）

Spark提供了一个独立的集群管理器，允许用户在不依赖于其他资源管理器的情况下部署Spark应用程序。用户可以通过启动和配置独立的Master和Worker节点来实现集群。

这种模式仅用于开发环境，生产环境使用Spark on YARN的方式

spark-sql

使用SparkSQL连接Spark Standalone

没有配置Spark on Hive持久存储，使用内存模式进入默认会在当前目录下生成 spark-warehouse 目录

spark-sql \
    --conf spark.sql.catalogImplementation=in-memory \
    --conf spark.sql.legacy.createHiveTableByDefault=false \
    --master spark://bigdata01:7077 \
    --total-executor-cores 2

创建数据库

CREATE TABLE my_table_spark (
    id INT,
    name STRING
);

插入数据

INSERT INTO my_table_spark VALUES
    (1, 'John'),
    (2, 'Jane'),
    (3, 'Bob'),
    (4, 'Alice');

查询数据

SELECT * FROM my_table_spark;
SELECT count(*) FROM my_table_spark;

清理目录
