                            添加JAR包到Hive的classpath中有如下三種方法。
**1. 使用 `add` 命令**
```sql
0: jdbc:hive2://hadoop101:10000> add jar /opt/software/udf-1.0-SNAPSHOT.jar;
```
該方法每次啟動 Hive 的時候都要重新加入，退出 hive 就會失效。
**2. 在{hive_home}/conf/hive-site.xml 文件配置 `hive.aux.jars.path`**
```xml
<property>
    <name>hive.aux.jars.path</name>
    <!--多個jar包用,隔開 -->
    <value>file:////opt/software/udf-1.0-SNAPSHOT001.jar,file:////opt/software/udf-1.0-SNAPSHOT002.jar</value>
</property>
```
**3. 在根目錄${HIVE_HOME}下創建文件夾 auxlib，然后將自定義 jar文件放入該文件夾中**
該方法方便快捷，不過對于客戶端操作環境就不能執行。
