   > > @leixm @smallzhongfeng @tsface Is there this problem? Do we need a pr to fix this issue?

   > @jerqi Currently, i have only tested version 0.6.0. Like I mentioned above, I just specified the `protobuf-java` version as `3.19.2` in the pom file.

   You're right, it's a problem, we avoid this problem by excluding protobuf-java in the internal version, like:
   `client-spark/spark3/pom.xml`
   ```xml
           <dependency>
               <groupId>org.apache.spark</groupId>
               <artifactId>spark-core_${scala.binary.version}</artifactId>
               <version>${spark.version}</version>
               <scope>provided</scope>
               <exclusions>
                   <exclusion>
                       <groupId>com.google.protobuf</groupId>
                       <artifactId>protobuf-java</artifactId>
                   </exclusion>
               </exclusions>
           </dependency>
   ```
