CQL复制到Cassandra表不起作用

我有一个tsv文件，记录如下：

"county_id" "county_desc"   "voter_reg_num" "status_cd" "voter_status_desc" "reason_cd" "voter_status_reason_desc"  "absent_ind"    "name_prefx_cd" "last_name" "first_name"    "middle_name"   "name_suffix_lbl"   "res_street_address"    "res_city_desc" "state_cd"  "zip_code"  "mail_addr1"    "mail_addr2"    "mail_addr3"    "mail_addr4"    "mail_city" "mail_state"    "mail_zipcode"  "full_phone_number" "race_code" "ethnic_code"   "party_cd"  "gender_code"   "birth_age" "birth_state"   "drivers_lic"   "registr_dt"    "precinct_abbrv"    "precinct_desc" "municipality_abbrv"    "municipality_desc" "ward_abbrv"    "ward_desc" "cong_dist_abbrv"   "super_court_abbrv" "judic_dist_abbrv"  "nc_senate_abbrv"   "nc_house_abbrv"    "county_commiss_abbrv"  "county_commiss_desc"   "township_abbrv"    "township_desc" "school_dist_abbrv" "school_dist_desc"  "fire_dist_abbrv"   "fire_dist_desc"    "water_dist_abbrv"  "water_dist_desc"   "sewer_dist_abbrv"  "sewer_dist_desc"   "sanit_dist_abbrv"  "sanit_dist_desc"   "rescue_dist_abbrv" "rescue_dist_desc"  "munic_dist_abbrv"  "munic_dist_desc"   "dist_1_abbrv"  "dist_1_desc"   "dist_2_abbrv"  "dist_2_desc"   "confidential_ind"  "age"   "ncid"  "vtd_abbrv" "vtd_desc"

这个模式是：

);

当我尝试复制到cassandra表时，使用：

COPY voters FROM 'sample.tsv' WITH DELIMITER='\t';

我得到：

Processed: 1000 rows; Rate:    1230 rows/s; Avg. rate:    1945 rows/s
1000 rows imported from 1 files in 0.514 seconds (0 skipped).

但是，当我进行计数时，我发现只有一条记录被复制到表中

我做错了什么？提前谢谢

如果tsv文件的列名称位于顶部，那么不要忘记将HEADER=TRUE添加到COPY命令中。我还将删除双引号，并验证字段是否由制表符而不是空格分隔。要进行测试，只需创建一个新的tsv文件，其中包含50行左右的原始内容，并在其中进行更改。让我知道进展如何。

使用copy命令添加列名

COPY voters(county_id,county_desc,voter_reg_num,status_cd,voter_status_desc,reason_cd,voter_status_reason_desc,absent_ind,name_prefx_cd,last_name,first_name,middle_name,name_suffix_lbl,res_street_address,res_city_desc,state_cd,zip_code,mail_addr1,mail_addr2,mail_addr3,mail_addr4,mail_city,mail_state,mail_zipcode,full_phone_number,race_code,ethnic_code,party_cd,gender_code,birth_age,birth_state,drivers_lic,registr_dt,precinct_abbrv,precinct_desc,municipality_abbrv,municipality_desc,ward_abbrv,ward_desc,cong_dist_abbrv,super_court_abbrv,judic_dist_abbrv,nc_senate_abbrv,nc_house_abbrv,county_commiss_abbrv,county_commiss_desc,township_abbrv,township_desc,school_dist_abbrv,school_dist_desc,fire_dist_abbrv,fire_dist_desc,water_dist_abbrv,water_dist_desc,sewer_dist_abbrv,sewer_dist_desc,sanit_dist_abbrv,sanit_dist_desc,rescue_dist_abbrv,rescue_dist_desc,munic_dist_abbrv,munic_dist_desc,dist_1_abbrv,dist_1_desc,dist_2_abbrv,dist_2_desc,confidential_ind,age,ncid,vtd_abbrv,vtd_desc) FROM 'sample.tsv' WITH DELIMITER='\t' AND HEADER = true;

你的模式是什么？@AshrafulIslam我用这个模式更新了问题，忘了写header=true条件。我创建了一个有50行的文件，并像你说的那样删除了双引号，但现在我有另一个问题。一些空字段消失了，然后我得到了以下结果：导入1行失败：ParseError-无效行长度70应为71，放弃而不重试导入4行失败：ParseError-无效行长度69应为71，放弃而不重试处理5行失败；写入导入|测试"投票者的行失败。错误如果更改为|或逗号分隔并删除引号，错误是否仍然存在？我不确定您对如何生成TSV文件有多大的控制权，因此这可能不是一种实用的方法。看起来标题和表中的列是按顺序排列的。只有一行被导入的一种情况是主键在所有方面都是相同的，但这里的情况似乎不是这样。这对我不起作用，我仍然有以下错误

导入x行失败：ParseError-无效的行长度y应该是z，不重试就放弃了
。但是我用命令行告诉你gave@Marine1相同的数据？
