创建外部配置单元表时，在错误配置单元（yatish）下获取

CREATE EXTERNAL TABLE yatish_h1b_data_ak 
(    
     ID:INT,
     CASE_STATUS:VARCHAR,
     EMPLOYER_NAME:VARCHAR,
     SOC_NAME:VARCHAR,
     JOB_TITLE:VARCHAR,
     FULL_TIME_POSITION:VARCHAR,
     PREVAILING_WAGE:FLOAT,
     YEAR:INT,
     WORKSITE:VARCHAR,
     LONGITUDE:VARCHAR,
     LATITUDE:VARCHAR 
)
ROW FORMAT DELIMITED              
FIELDS TERMINATED BY \073' LINE TERMINATED BY '\n'              
LOCATION user/seethayatish/yatish;

您错误地编写了create table语句。字段名与其数据类型之间没有冒号（：）。只需在字段名和它的数据类型之间保留空格。此外，配置单元中不支持varchar和float类型，而是使用string和double。
以下是正确的陈述：

CREATE EXTERNAL TABLE yatish_h1b_data_ak ( 

ID                   INT,
CASE_STATUS          STRING,
EMPLOYER_NAME        STRING,
SOC_NAME             STRING,
JOB_TITLE            STRING,
FULL_TIME_POSITION   STRING,
PREVAILING_WAGE      FLOAT,
YEAR                 INT,
WORKSITE             STRING,
LONGITUDE            STRING,
LATITUDE             STRING ) 

ROW FORMAT DELIMITED  

FIELDS TERMINATED BY '\073' 

LINES TERMINATED BY '\n' 

LOCATION '/user/seethayatish/yatish';
