spark_spark连接hive config
1 环境
hadoop2.7.3
apache-hive-2.1.1-bin
spark-2.1.0-bin-hadoop2.6
jdk1.8
2 配置文件
在hive-site.xml中配置mysql数据库连接。
cp apache-hive-2.1.1-bin/conf/hive-site.xml ./spark-2.1.0-bin-hadoop2.6/conf/
cp apache-hive-2.1.1-bin/lib/mysql-connector-java-5.1.40-bin.jar ./spark-2.1.0-bin-hadoop2.6/jars
3 启动
启动hadoop : ./hadoop-2.7.3/sbin/start-all.sh
启动mysql : service mysql start
启动hive : ./apache-hive-2.1.1-bin/bin/hive
启动spark : ./spark-2.1.0-bin-hadoop2.6/bin/spark-sql 验证是否正常连接hive,查询语法同hive一致。 (i.e. show tables;)
或者 ./spark-2.1.0-bin-hadoop2.6/bin/spark-shell 运行scala程序
