一、遇到问题
离线数仓 hive on spark 模式，hive 客户端 sql 插入数据报错
Failed to execute spark task, with exception 'org.apache.hadoop.hive.ql.metadata.HiveException(Failed to create Spark client for Spark session 50cec71c-2636-4d99-8de2-a580ae3f1c58)'

以下是报错详情：

二、排查过程：
0、确认 hive、spark 版本
hive3.1.2：apache-hive-3.1.2-bin.tar.gz （重新编译之后的）
spark3.0.0：
+spark-3.0.0-bin-hadoop3.2.tgz
+spark-3.0.0-bin-without-hadoop.tgz
兼容性说明
注意：官网下载的 Hive 3.1.2 和 Spark 3.0.0 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。
1、确认 SPARK_HOME 环境变量
[hadoop@hadoop102 software]$ sudo vim /etc/profile.d/my_env.sh
添加如下内容
SPARK_HOME
export SPARK_HOME=/opt/module/spark
export PATH=$PATH:$SPARK_HOME/bin
source 使其生效
[hadoop@hadoop102 software]$ source /etc/profile.d/my_env.sh
2、hive 创建的 spark 配置文件
在hive中创建spark配置文件
[atguigu@hadoop102 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）
spark.master yarn
spark.eventLog.enabled true
spark.eventLog.dir hdfs://hadoop102:8020/spark-history
spark.executor.memory 1g
spark.driver.memory 1g
3、确认是否创建 hdfs 存储历史日志路径
确认存储历史日志路径是否创建
[hadoop@hadoop102 conf]$ hdfs dfs -ls /
Found 4 items
drwxr-xr-x - hadoop supergroup 0 2022-07-28 20:31 /spark-history
drwxr-xr-x - hadoop supergroup 0 2022-03-15 16:42 /test
drwxrwx--- - hadoop supergroup 0 2022-03-16 09:14 /tmp
drwxrwxrwx - hadoop supergroup 0 2022-07-28 18:38 /user
若不存在，则需要在HDFS创建如下路径
[hadoop@hadoop102 software]$ hadoop fs -mkdir /spark-history
4、确认 是否上传 Spark 纯净版 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。
[hadoop@hadoop102 software]$ tar -zxvf /opt/software/spark-3.0.0-bin-without-hadoop.tgz
上传Spark纯净版jar包到HDFS
[hadoop@hadoop102 software]$ hadoop fs -mkdir /spark-jars
[hadoop@hadoop102 software]$ hadoop fs -put spark-3.0.0-bin-without-hadoop/jars/* /spark-jars
5、确认 hive-site.xml 配置文件
[hadoop@hadoop102 ~]$ vim /opt/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://hadoop102:8020/spark-jars/*</value>
</property>
<!--Hive执行引擎-->
<property>
<name>hive.execution.engine</name>
<value>spark</value>
</property>
三、解决问题
在 hive/conf/hive-site.xml中追加：
（这里延长了 hive 和 spark 连接的时间，可以有效避免超时报错）
<!--Hive和spark连接超时时间-->
<property>
<name>hive.spark.client.connect.timeout</name>
<value>100000ms</value>
</property>
这时，重新打开 hive 客户端，插入数据正常无报错
[hadoop@hadoop102 conf]$ hive
which: no hbase in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/datafs/module/jdk1.8.0_212/bin:/datafs/module/hadoop-3.1.3/bin:/datafs/module/hadoop-3.1.3/sbin:/datafs/module/zookeeper-3.5.7/bin:/datafs/module/kafka/bin:/datafs/module/flume/bin:/datafs/module/mysql-5.7.35/bin:/datafs/module/hive/bin:/datafs/module/spark/bin:/home/hadoop/.local/bin:/home/hadoop/bin)
