Null handling issue
Posted: Mon Dec 12, 2011 7:01 am
Hi all,
I have job design where data is written to seq file with "UNKNOWN" whwerever null is coming from the source.
While reading the file given null field value='UNKNOWN' in format tab so this will convert all 'UNKNOWN' data to null in seq file.
My source data coming as 'UNKNOWN' ,so my confusion is do 'UNKNOWN'(Src null) match with seq. file data i.e. null.
Regards
