Hive和Spark生产集群搭建（spark on doris）

1.环境准备

1.1 版本选择

序号	bigdata-001	bigdata-002	bigdata-003	bigdata-004	bigdata-005
MySQL-8.0.31	mysql
Datax	Datax	Datax	Datax	Datax	Datax
Spark-3.3.1	Spark	Spark	Spark	Spark	Spark
Hive-3.1.3	Hive	Hive

1.2 主要组件官网

hive官网： https://hive.apache.org/
hive安装包下载：http://archive.apache.org/dist/hive/
spark官网：https://spark.apache.org/
spark安装包下载：https://www.apache.org/dyn/closer.lua/spark/spark-3.3.1/

注意：官网下载的Hive3.1.3和Spark3.3.1默认是不兼容的。因为Hive3.1.3支持的Spark版本是2.4.5，所以需要我们重新编译Hive3.1.3版本。

2.Hive安装部署

2.1 环境配置

1. 解压apache-hive-3.1.3-bin.tar.gz到/data/module/目录下面

[hadoop@hadoop1 software]$ tar -zxvf /data/software/apache-hive-3.1.3-bin.tar.gz -C /data/module/

2. 修改apache-hive-3.1.3-bin.tar.gz的名称为hive

[hadoop@hadoop1 software]$ mv /data/module/apache-hive-3.1.3-bin/ /data/module/hive-3.1.3

3. 修改/etc/profile.d/my_env.sh，添加环境变量

[hadoop@hadoop1 software]$ sudo vim /etc/profile.d/my_env.sh

4. 添加内容

#HIVE_HOME
export HIVE_HOME=/data/module/hive-3.1.3
export PATH=$PATH:$HIVE_HOME/bin
export PATH JAVA_HOME HADOOP_HOME HIVE_HOME

2.2 Hive元数据配置到MySQL

1. 拷贝mysql的jdbc驱动(mysql-connector-java-5.1.48.jar)到hive的lib目录下

[hadoop@hadoop1 software]$ cp /data/software/mysql-connector-java-5.1.48.jar $HIVE_HOME/lib

2. 配置Metastore到MySql
   在$HIVE_HOME/conf目录下新建hive-site.xml文件

[hadoop@hadoop1 software]$ vim $HIVE_HOME/conf/hive-site.xml

添加如下内容

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration><!-- jdbc连接的URL --><property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://xxx:3306/metastore?useSSL=false&amp;createDatabaseIfNotExist=true&amp;characterEncoding=UTF-8</value>

2.3 初始化元数据库

1. 登陆MySQL

[hadoop@hadoop1 software]$ mysql -uroot -pxxx

2. 新建Hive元数据库

mysql> create database metastore;
mysql> quit;

3. 初始化Hive元数据库

[hadoop@hadoop1 software]$ schematool -initSchema -dbType mysql -verbose

4） 修改元数据库字符集
Hive元数据库的字符集默认为Latin1，由于其不支持中文字符，故若建表语句中包含中文注释，会出现乱码现象。如需解决乱码问题，须做以下修改。
修改Hive元数据库中存储注释的字段的字符集为utf-8
//字段注释

mysql> alter table COLUMNS_V2 modify column COMMENT varchar(256) character set utf8;
//表注释
mysql> alter table TABLE_PARAMS modify column PARAM_VALUE mediumtext character set utf8;
//退出
quit;

4. hadoop的配置文件core-site.xml和hdfs-site.xml复制到hive的conf中

2.4 启动metastore和hiveserver2

1. 启动hiveserver2

[hadoop@hadoop1 hive]$ bin/hive --service hiveserver2

2. 启动beeline客户端（需要多等待一会）

[hadoop@hadoop1 hive]$ bin/beeline -u jdbc:hive2://hadoop1:10000 -n hadoop

3. 看到如下界面

Connecting to jdbc:hive2://hadoop1:10000
Connected to: Apache Hive (version 3.1.2)
Driver: Hive JDBC (version 3.1.2)
Transaction isolation: TRANSACTION_REPEATABLE_READ
Beeline version 3.1.2 by Apache Hive
0: jdbc:hive2://hadoop1:10000>

3.Spark安装

3.1 解压缩文件

将spark-3.3.1-bin-hadoop3.tgz文件上传到Linux并解压缩，放置在指定位置，路径中不要包含中文或空格

tar -zxvf spark-3.3.1-bin-hadoop3.tgz -C /data/module
cd /data/module 
mv spark-3.3.1-bin-hadoop3.2  spark-3.3.1

3.2 启动环境

1)进入解压缩后的路径，执行如下指令

bin/spark-shell

2. 启动成功后，可以输入网址进行Web UI监控页面访问
   http://hadoop1:4040

3.3 Hive on Spark配置

3.3.1 配置SPARK_HOME环境变量

[hadoop@hadoop1 software]$ sudo vim /etc/profile.d/my_env.sh

添加如下内容

# SPARK_HOME
export SPARK_HOME=/data/module/spark-3.3.1
export PATH=$PATH:$SPARK_HOME/bin

source 使其生效

[hadoop@hadoop1 software]$ source /etc/profile.d/my_env.sh

3.3.2 创建spark配置文件并复制到hive中

[hadoop@hadoop1 software]$ vim /data/module/spark-3.3.1
/conf/spark-defaults.conf

添加如下内容（在执行任务时，会根据如下参数执行）

spark.master                               yarn
spark.eventLog.enabled                   true
spark.eventLog.dir    hdfs://yourhadoopcluster/spark-history
spark.executor.cores    1
spark.executor.memory    4g
spark.executor.memoryOverhead    2g
spark.driver.memory    4g
spark.driver.memoryOverhead    2g
spark.dynamicAllocation.enabled  true
spark.shuffle.service.enabled  true
spark.dynamicAllocation.executorIdleTimeout  60s
spark.dynamicAllocation.initialExecutors    1
spark.dynamicAllocation.minExecutors  1
spark.dynamicAllocation.maxExecutors  12
spark.dynamicAllocation.schedulerBacklogTimeout 1s
spark.dynamicAllocation.sustainedSchedulerBacklogTimeout 5s
spark.dynamicAllocation.cachedExecutorIdleTimeout 30s
spark.shuffle.useOldFetchProtocol    true
spark.history.fs.cleaner.enabled    true
spark.history.fs.cleaner.interval    1d
spark.history.fs.cleaner.maxAge    7d
spark.hadoop.orc.overwrite.output.file true
spark.executor.extraJavaOptions=-Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8
spark.driver.extraJavaOptions=-Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8

在HDFS创建如下路径，用于存储历史日志

[hadoop@hadoop1 software]$ hadoop fs -mkdir /spark-history

3.3.4 向HDFS上传Spark纯净版jar包

说明1：由于Spark3.3.1非纯净版默认支持的是hive2.3.7版本，直接使用会和安装的Hive3.1.2出现兼容性问题。所以采用Spark纯净版jar包，不包含hadoop和hive相关依赖，避免冲突。

说明2：Hive任务最终由Spark来执行，Spark任务资源分配由Yarn来调度，该任务有可能被分配到集群的任何一个节点。所以需要将Spark的依赖上传到HDFS集群路径，这样集群中任何一个节点都能获取到。

① 上传并解压spark-3.3.1-bin-without-hadoop.tgz

[hadoop@hadoop1 software]$ tar -zxvf /data/software/spark-3.3.1-bin-without-hadoop.tgz

② 上传Spark纯净版jar包到HDFS

[hadoop@hadoop1 software]$ hadoop fs -mkdir /spark-jars[hadoop@hadoop1 software]$ hadoop fs -put spark-3.3.1-bin-without-hadoop/jars/* /spark-jarscp /data/module/spark-3.3.1/yarn/spark-3.3.1-yarn-shuffle.jar /data/module/hadoop-3.3.4/share/hadoop/yarn/lib/

6)将spark的jar包拷贝到yarn中

cp /data/module/spark-3.3.1/yarn/spark-3.3.1-yarn-shuffle.jar /data/module/hadoop-3.3.4/share/hadoop/yarn/lib/

3.3.5 修改hive-site.xml文件（以上已配置）

[hadoop@hadoop1 ~]$ vim /data/module/hive/conf/hive-site.xml
添加如下内容
<!--Spark依赖位置（注意：端口号8020必须和namenode的端口号一致）-->
<property><name>spark.yarn.jars</name><value>hdfs://xxx:8020/spark-jars/*</value>
</property><!--Hive执行引擎-->
<property><name>hive.execution.engine</name><value>spark</value>
</property>

3.3.6 spark-sql操作doris

下载git代码库的spark代码：https://github.com/apache/doris-spark-connector
按照readme介绍打包自己的适配版连接器jar包
将jar包复制到spark的jars目录下，同时hdfs上的spark包目录也上传一份

cp /your_path/spark-doris-connector/target/spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar  $SPARK_HOME/jars
hadoop fs -put /your_path/spark-doris-connector/target/spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar /spark-jars

运行spark-sql 测试：

//测试
CREATE
TEMPORARY VIEW spark_doris1
USING doris
OPTIONS('table.identifier'='demo.t1','fenodes'='xxx:8030','user'='xxx','password'='xxx'
);
CREATE
TEMPORARY VIEW spark_doris2
USING doris
OPTIONS('table.identifier'='demo.t2','fenodes'='xxx:8030','user'='xxx','password'='xxx'
);INSERT INTO spark_doris1
select * from spark_doris2;
