将csv文件（空值）导入cassandra时出现异常错误

我正在尝试将csv文件导入Cassandra。我的桌子是空的

copy info_by_vinid_search (vin_id,vinnumber,vin_start_date,vin_stop_date,cartype,bi_symbol,mercury_liability_symbol,pip_symbol,driving_wheels,cylinders,brakes,antitheft_code,daytime_lamps_ind, restraint,vsr_symbol_id,base_list_price,bodystyle_id,model_id,make_id,make_symbol,model_symbol,style_symbol,aux_symbol,polk_make,polk_model,polk_bodystyle,polk_engine_info_turbocharged,comp_symbol,coll_symbol,mb_symbol,ev_indicator,year,make,ncic_code,model,bodystyle,symbol_twodigit)FROM '36_vinid.csv' WITH DELIMITER = ',' AND HEADER=TRUE; 

当我运行上面的copy命令时，它抛出以下异常：

Process Process-21:
Traceback (most recent call last):
  File "/usr/lib64/python2.6/multiprocessing/process.py", line 232, in _bootstrap

  File "./cqlsh", line 1703, in multiproc_import
    cqltypes = [table_meta.columns[name].typestring for name in columns]
KeyError: 'antitheft_code'

表架构：

我确实导入了许多没有空值的csv文件。我可以把数据导入卡桑德拉。是否由于csv文件中存在空值而发生异常。我有什么遗漏吗？请帮忙

谢谢

你能发布你的表格定义吗

此外，您的文件看起来是逗号分隔的，但是您的头看起来是制表符分隔的。您需要告诉COPY您的头存在（

且header=true

）。

是。。你说得对。在复制和更新时，我确实忽略了这一点。@Aaron，复制命令中的表架构和属性不匹配。这导致了异常。我确实修复了它，并且能够加载数据。非常感谢你的帮助。太好了！将我的评论转换为答案。。。
