我正在尝试使用sqoop hcatlog（见下文）从netezza db导入一个orc格式的表
sqoop命令：

sqoop import
-m 1
--connect <jdbc_url>
--driver <database_driver>
--connection-manager org.apache.sqoop.manager.GenericJdbcManager
--username <db_username>
--password <db_password>
--table <table_name>
--hcatalog-home /usr/hdp/current/hive-webhcat
--hcatalog-database <hcat_db>
--hcatalog-table < table_name >
--create-hcatalog-table
--hcatalog-storage-stanza 'stored as orc tblproperties ("orc.compress"="SNAPPY")';

但是，它失败了，出现了以下异常。在花了几个小时之后，我不知道它为什么会失败。如有任何帮助/线索，我们将不胜感激。

更新：我可以看到，虽然源表有200k条记录，但还是创建了空表。有解决这个问题的建议吗？
