hive udf, tried to access method org.bouncycastle.math.ec.ECPoint$AbstractFp

在hive中添加加密udf,测试报错：

select encrypt_sm2("aa","04AD9356466C7A505B3B2E18F2484E1F096108FA19C0F61C707A808EDF7C132BC3CE33E63D2CC6D77FB0A172004F8F5282CEADE22ED9628A02FE8FD85AF1EFE8B3");

加密算法包版本：

<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.57</version>
</dependency>

根据异常，发现方法调用没权限，本地测试是正常的，猜测应该是包冲突了；

linux上查看是否有其他jar包：

locate bcprov

发现hadoop lib里有该jar包,版本不一致，变更版本后，有些方法不兼容了，遂查询了下是否兼容两个包的方法；

找了下，可以变更下包名，兼容加载：

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-shade-plugin</artifactId>
			 <version>3.2.1</version>
			 <configuration>
             <!-- 改为true -->  
			 <createDependencyReducedPom>true</createDependencyReducedPom>
			 </configuration>
			 <executions>
				 <execution>
					 <!-- Maven 的生命周期 -->
					 <phase>package</phase>
					 <goals>
					 <!-- 插件目标 -->
					 <goal>shade</goal>
					 </goals>
		    <configuration>
				<!-- <minimizeJar>true</minimizeJar>-->
				 <!-- 配置多版本 jar 包中类路径的重命名
 					-->
			 <relocations>
				 <relocation>
					 <pattern>org.bouncycastle</pattern>
					 <shadedPattern>org.new.bouncycastle</shadedPattern>
				 </relocation>
			 </relocations>
			 <filters>
				 <filter>
					 <artifact>*:*</artifact>
				 <excludes>
				 <exclude>META-INF/*.SF</exclude>
				 <exclude>META-INF/*.DSA</exclude>
				 <exclude>META-INF/*.RSA</exclude>
				 </excludes>
				 </filter>
				 </filters>
 				</configuration>
		 </execution>
		</executions>
 </plugin>
