Apache Hive：失败：ParseException line 4:1 character '' 此处不支持

编程问答 2022-08-11

问题描述

我正在尝试在 Apache Hive 中创建一个新表，该表从 CSV 文件加载数据。 我写了这个脚本

CREATE SCHEMA IF NOT EXISTS practica2;

CREATE EXTERNAL TABLE IF NOT EXISTS practica2.station_data 
(IDPROVINCIA string,SPROVINCIA string,IDESTACION string,SESTACION string,FECHA string,DIA string,TEMPMAX string,HORMINTEMPMAX string,TEMPMIN string,HORMINTEMPMIN string,TEMPMEDIA string,HUMEDADMAX string,HUMEDADMIN string,HUMEDADMEDIA string,VELVIENTO string,DIRVIENTO string,RADIACION string,PRECIPitacION string) 
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ';'
STORED AS TEXTFILE
LOCATION 'hdfs://0.0.0.0:9000/user/hive';

但是，当我执行脚本时，出现此错误

Failed: ParseException line 4:1 character '' not supported here

我用另一种替代方法进行了测试，结果相同：

CREATE SCHEMA IF NOT EXISTS practica2;

CREATE TABLE IF NOT EXISTS practica2.station_data 
(IDPROVINCIA string,PRECIPitacION string) 
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ';';

LOAD DATA LOCAL INPATH './RIA_exportacion_datos_diarios_Huelva_20140206.csv' INTO TABLE practica2.station_data;

完整报告如下：

almu@debian:~/Practicas_BigData/Practica2/Hive$ hive -f practica2.hql

当我从 Hive 命令行创建表时，它的创建没有问题。但是，当我执行脚本时，它总是失败。

错误在哪里？

更新：关于“;”的建议可能是错误的原因，我像这样替换了这一行：

FIELDS TERMINATED BY ',';

但错误仍在继续

解决方法

尝试删除新行？

CREATE SCHEMA IF NOT EXISTS practica2;

CREATE EXTERNAL TABLE IF NOT EXISTS practica2.station_data (IDPROVINCIA string,SPROVINCIA string,IDESTACION string,SESTACION string,FECHA string,DIA string,TEMPMAX string,HORMINTEMPMAX string,TEMPMIN string,HORMINTEMPMIN string,TEMPMEDIA string,HUMEDADMAX string,HUMEDADMIN string,HUMEDADMEDIA string,VELVIENTO string,DIRVIENTO string,RADIACION string,PRECIPITACION string) 
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ';'
STORED AS TEXTFILE
LOCATION 'hdfs://0.0.0.0:9000/user/hive';

或者您的 sql 文件中可能有全角空间。见this post。如果你想去掉全角空格，手动输入sql文件，避免从其他地方复制/粘贴。
