错误信息如下：
org.datanucleus.metadata.InvalidClassmetaDataException: Class "org.apache.hadoop.hive.metastore.model.MDatabase" field "org.apache.hadoop.hive.metastore.model.MDatabase.catalogName" : declared in metaData, but this field doesnt exist in the class!
Caused by: org.datanucleus.exceptions.NucleusUserException: Identifier principalName is unresolved (not a static field)
}
解决方案：
找了很多资料，都没有解决，其实只是因为我忘记把hive-site.xml导入了
导入hive-site.xml即可
