 ### Hadoop Limitations
 
 Users can only use Hadoop `3.3.6` as the underlying Hadoop dependency of HiveServer2 JDBC Driver `4.0.1`.

+HiveServer2 JDBC Driver `4.0.1` does not support Hadoop `3.4.1`. Reference https://github.com/apache/hive/pull/5500 .
+
+For HiveServer2 JDBC Driver `org.apache.hive:hive-jdbc:4.0.1` or `org.apache.hive:hive-jdbc:4.0.1` with `classifier` as `standalone`,
+there is actually no additional dependency on `org.apache.hadoop:hadoop-mapreduce-client-core:3.3.6`.
+
+But `org.apache.shardingsphere:shardingsphere-infra-database-hive`'s
+`org.apache.shardingsphere.infra.database.hive.metadata.data.loader.HiveMetaDataLoader` uses `org.apache.hadoop.hive.conf.HiveConf`,
+which further uses `org.apache.hadoop:hadoop-mapreduce-client-core:3.3.6`'s `org.apache.hadoop.mapred.JobConf` class.
+
+ShardingSphere only needs to use the `org.apache.hadoop.mapred.JobConf` class,
