    I am running the following command using PigStorage, but the output is not separated with commas…
    grunt> A = Load ‘/user/Pavan/sample.txt’
    >> USING PigStorage(‘,’)
    >>as (sno:int, name:chararray, city:chararray);

    The output is :
    (1 Mary UK,,)
    (2 Alex Asia,, )
    (3 Roger US,,)

    Can anyone suggest how to produce correct output separated with commas??

    PigStorage(‘,’) tells pigstorage that the columns are separated by “,”. it looks like your input file is not comma separated.
    If the issue is something else, pasting the contents of the sample.txt and entire pig script might help.

    The sample text file contains the data:
    1 Mary UK
    2 Alex Asia
    3 Roger US

    The script i used is:
    grunt> A = load ‘/user/Pavan/sample.txt’
    >>USING PigStorage(‘,’)
    >>as (sno:chararray, name:chararray, city:chararray);

    Then ,,
    grunt> dump A;
    It produces the output,
    (1 Mary UK,,)
    (2 Alex Asia,,)
    (3 Roger US,,)
    When i used sandbox it worked fine and producing the comma separated output although the input file does not contain commas.
    But now i am using HDP on windows server 2008 R2. It is not giving the comma separated output.

    Also i am facing another issue..when i use the datatype in schema as int,
    the output is without the data as follows:
    (,,)
    (,,)
    (,,)

    Can you please suggest me why this is happening?????????

    Now the two issues resolved when modified the script as:
    grunt> A = load ‘/user/Pavan/sample.txt’
    >>USING PigStorage(‘ ’)
    >>as (sno:chararray, name:chararray, city:chararray);
    For PigStorage the comma is replaced with space.
