具体操作及错误信息我贴到下面，各位大佬帮忙看下如何解决，不知道是不是BUG。

scala> import org.apache.flink.table.catalog.hive.HiveCatalog
import org.apache.flink.table.catalog.hive.HiveCatalog

scala> val hiveCatalog = new HiveCatalog("hive", "mydatabase",
"/opt/hive2.3.3/conf", "2.3.3");
hiveCatalog: org.apache.flink.table.catalog.hive.HiveCatalog =
org.apache.flink.table.catalog.hive.HiveCatalog@193f3306

scala> btenv.registerCatalog("hive", hiveCatalog)
