Dear Russell,
My pig version is 0.91. I have tried a little bit. But I got a problem. My
data is looks like:
henrietta 1 25
sally 1 82
fred 2 120
elsie 3 45
tom 1 82
tom 4 98
sally 2 87
the delimiter is '\t'.
I use the command to load the data
A = LOAD '/home/yonghu/test/student.txt' AS
>> (name:chararray,B:{T1:(id:int,result:int)});
then I got the following errors:
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 2, column 42>
mismatched input ';' expecting RIGHT_PAREN
Details at logfile: /home/yonghu/pig-0.9.1/bin/pig_1339440832010.log
what does here right_paren mean? Is there any request of the input data?
Thanks.
Yong
