Hi Jingsong, Thanks to your pointer, I checked the dependencies and found out that it’s caused by the classloaders.
In my deployment, the hive connector (and its orc dependencies), which contains `DefaultBucketFactoryImpl`, was packaged into the job uber jar. On the other hand, the flink runtime, which contains `HadoopPathBasedBulkFormatBuilder ` is located in the lib folder. Since the two jars are loaded by different class loaders, the classes are considered under different packages. That’s why an `java.lang.IllegalAccessError` occurred. BTW, the artifact links of the hive connectors seem to be broken. Should we use https://repo.maven.apache.org/maven2/ <https://repo.maven.apache.org/maven2/> instead?
