Hi Srini,
You can use STRSPLIT to split your "value" chararray and define schema in a
FOREACH. For example, if the "value" consists of 3 integers (i.e. "1|2|3"),
A= LOAD 'part-m-0000' USING SequenceFileLoader() AS
(key:long,value:chararray);
B = FOREACH A GENERATE key, FLATTEN( STRSPLIT(value,'\\|') ) AS (i:int,
j:int, k:int);
DESCRIBE B;
DUMP B;
This will return:
B: {key: chararray,i: int,j: int,k: int}
(k,1,2,3)
Thanks,
Cheolsoo
