Hi Folks,
I am very new to PIG. I am facing problems in using DiffDate function
present in org.apache.pig.piggybank.
evaluation.datetime.
How do I pass 2 dates in a tuple format?
I get an error.
This is what I do:
A= LOAD 'date.csv' AS (t1:tuple(t1a:chararray, t1b:chararray));
DESCRIBE A;
DUMP A;
tooutput = FOREACH A GENERATE
org.apache.pig.piggybank.evaluation.datetime.DiffDate(t1) AS
diffrerence:int;
describe tooutput;
The date.csv has 1 line as follows:
("20110920","20110918")
The error message:
2011-08-18 03:41:10,922 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1045: Could not infer the matching function for
org.apache.pig.piggybank.evaluation.datetime.DiffDate as multiple or none of
them fit. Please use an explicit cast.
What am I doing wrong in the code snippet above?
The pig version which I use is 0.8.0-CDH3B4
Thanks a lot,
Rekha
