问题
I have a dataset as follows,
John Doe^A100000.0^AMary Smith^BTodd Jones^AFederal Taxes^C.2^BState Taxes^C.05^BInsurance^C.1^A1 Michigan Ave.^BChicago^BIL^B60600
Mary Smith^A80000.0^ABill King^AFederal Taxes^C.2^BState Taxes^C.05^BInsurance^C.1^A100 Ontario St.^BChicago^BIL^B60601 Todd Jones^A70000.0^AFederal Taxes^C.15^BState Taxes^C.03^BInsurance^C.1^A200 Chicago Ave.^BOak Park^BIL^B60700
Bill King^A60000.0^AFederal Taxes^C.15^BState Taxes^C.03^BInsurance^C.1^A300 Obscure Dr.^BObscuria^BIL^B60100
I have read in Hive documentation on "Text Encoding of Data values" on how hive decodes dataset having different "delimiters". For the above dataset, I have created a table with following schema,
CREATE TABLE employees
(
name STRING,
salary FLOAT,
subordinates ARRAY<STRING>,
deductions MAP<STRING, FLOAT>,
address STRUCT<street:STRING, city:STRING, state:STRING, zip:INT>
)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\001'
COLLECTION ITEMS TERMINATED BY '\002'
MAP KEYS TERMINATED BY '\003'
LINES TERMINATED BY '\n'
STORED AS TEXTFILE;
But the dataset is not being imported properly into the table.
|employees.name|employees.salary|employees.subordinates|employees.deductions|employees.address|
|--------------|----------------|----------------------|--------------------|-----------------|
|John Doe|NULL|["AMary Smith"]|{"BTodd Jones":null}|("street":"AFederal Taxes","city":null,"state":null,"zip":null}|
|Mary Smith|NULL|["ABill King"]|{"AFederal Taxes":null}|{"street":"C.2","city":null,"state":null,"zip":null}|
|Bill King|NULL|["AFederal Taxes"]|{"C.15":null}|{"street":"BState Taxes","city":null,"state":null,"zip":null} |
Can anyone please explain me why this is getting wrong though I am following as per documentation example in Page 45? Thanks in advance.
