Hive3 on Spark3配置

1、软件环境

1.1 大数据组件环境

大数据组件 版本
Hive 3.1.2
Spark spark-3.0.0-bin-hadoop3.2

1.2 操作系统环境

OS 版本
MacOS Monterey 12.1
Linux - CentOS 7.6

2、大数据组件搭建

2.1 Hive环境搭建

1)Hive on Spark说明

Hive引擎包括:默认 mrsparkTez
Hive on Spark :Hive既作为存储元数据又负责SQL的解析优化,语法是HQL语法,执行引擎变成了Spark,Spark负责采用RDD执行。
Spark on Hive : Hive只作为存储元数据,Spark负责SQL解析优化,语法是Spark SQL语法,Spark负责采用RDD执行。

2)Hive on Spark配置

(1)兼容性说明

注意:官网下载的Hive3.1.2和Spark3.0.0默认是不兼容的。因为Hive3.1.2支持的Spark版本是2.4.5,所以需要我们重新编译Hive3.1.2版本。
编译步骤:官网下载Hive3.1.2源码,修改pom文件中引用的Spark版本为3.0.0,如果编译通过,直接打包获取jar包。如果报错,就根据提示,修改相关方法,直到不报错,打包获取jar包。

(2)在Hive所在节点部署Spark

如果之前已经部署了Spark,则该步骤可以跳过。
Spark官网下载jar包地址

http://spark.apache.org/downloads.html
上传并解压解压spark-3.0.0-bin-hadoop3.2.tgz

[postman@cdh01 software]$ tar -zxvf spark-3.0.0-bin-hadoop3.2.tgz -C /opt/module/
[postman@cdh01 software]$ mv /opt/module/spark-3.0.0-bin-hadoop3.2 /opt/module/spark

(3)配置SPARK_HOME环境变量

[postman@cdh01 software]$ sudo vim /etc/profile.d/my_env.sh

添加如下内容。

shell 复制代码
# SPARK_HOME
export SPARK_HOME=/opt/module/spark
export PATH=$PATH:$SPARK_HOME/bin

使其生效:

source ${环境变量文件}

shell 复制代码
# For MacOS
[postman@cdh01 software]$ source ~/.zshrc

# For CentOS
[postman@cdh01 software]$ source /etc/profile.d/my_env.sh

(4)在hive中创建spark配置文件

shell 复制代码
[postman@cdh01 software]$ vim /opt/module/hive/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)。

shell 复制代码
spark.master                             yarn
spark.eventLog.enabled                   true
spark.eventLog.dir                       hdfs://cdh01:8020/spark-history
spark.executor.memory                    1g
spark.driver.memory					     1g

在HDFS创建如下路径,用于存储历史日志。

shell 复制代码
[postman@cdh01 software]$ hadoop fs -mkdir /spark-history

(5)向HDFS上传Spark无 hadoop+hive 依赖的纯净jar包

  • 说明1:由于Spark3.0.0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。

上传并解压spark-3.0.0-bin-without-hadoop.tgz

shell 复制代码
[postman@cdh01 software]$ tar -zxf /opt/software/spark-3.0.0-bin-without-hadoop.tgz

上传Spark纯净版jar包到HDFS

shell 复制代码
[postman@cdh01 software]$ hadoop fs -mkdir -p /spark-jars
[postman@cdh01 software]$ hadoop fs -put spark-3.0.0-bin-without-hadoop/jars/* /spark-jars

(6)修改hive-site.xml文件

shell 复制代码
[postman@cdh01 ~]$ vim /opt/module/hive/conf/hive-site.xml

添加如下内容。

xml 复制代码
<!--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://cdh01:8020/spark-jars/*</value>
</property>
  
<!--Hive执行引擎-->
<property>
    <name>hive.execution.engine</name>
    <value>spark</value>
</property>

7)修改 $SPARK_HOME/conf/spark-env.sh 文件

shell 复制代码
[postman@cdh01 ~]$ vim $SPARK_HOME/conf/spark-env.sh

添加如下内容。

shell 复制代码
export SPARK_DIST_CLASSPATH=$(hadoop classpath)

否则将报各类hadoop依赖包缺失的异常,如log4j、Hadoop的Configuration等包缺失。

2.2 Hive on Spark测试

(1)启动hive客户端

shell 复制代码
[postman@cdh01 hive]$ bin/hive

(2)创建一张测试表

shell 复制代码
hive (default)> create table user(id int, name string);

(3)通过insert测试效果

shell 复制代码
hive (default)> insert into table user values(1001,'zhangsan');

若结果如下,则说明配置成功。

shell 复制代码
hive (default)> insert into table user values(1001,'zhangsan');
Query ID = user_20231108165919_9908b655-96a7-4ccb-bb62-4dde28df9394

3、安装过程中的错误

3.1 M1芯片下 zstd 库文件错误

当执行 MR 类 sql 如 "insert into table user values(1001,'zhangsan'); " 时,程序在 Console 上长时间卡住,但无错误日志输出,此时日志格式为:

shell 复制代码
hive (default)> insert into table student values(1,'abc');

在"Ctrl + C"取消 sql 执行之前,去 yarn 控制页面查看了一下程序运行的结果:

在WebUI 页面上从某次失败 Application 的某次 MR 任务的执行 log 中,发现有如下错误:

shell 复制代码
Caused by: java.lang.UnsatisfiedLinkError: no zstd-jni in java.library.path
Unsupported OS/arch, cannot find /darwin/aarch64/libzstd-jni.dylib or load zstd-jni from system libraries. Please try building from source the jar or providing libzstd-jni in your system.

       at java.lang.System.loadLibrary(System.java:1657)

       at com.github.luben.zstd.Zstd.decompressedSize(Zstd.java:579)

同时在 Hadoop ResourceManager 的运行日志中也发现了关于这块的报错日志。

从上述 log 中可以看出zstd 软件库包(作用:文件压缩)在 M1 芯片下 不能很高的被支持,结合 Hive On Spark 运行的库包路径查找比对,最终在上传到HDFS集群路径/spark-jars 下 Hive on Spark的依赖jar 包中发现了 zstd jar 包:

  • zstd-jni-1.4.4-3.jar

经查,此前已有开发者在 zstd 的github项目 下上报过这个问题,且有网友反馈在"1.4.9-1"版本中已修复了该问题。

于是在 mvnrepository 网站 上下载版本的 jar 包:

  • zstd-jni-1.4.9-1.jar

之后,将 HDFS 路径"hdfs://cdh01:8020/spark-jars/*"下的原始 "zstd-jni-1.4.4-3.jar" 删除,并替换为 "zstd-jni-1.4.9-1.jar" 后(如上图所示),经再度测试,该问题就解决了。
