I have a parallel job which designed in such a way that,
Code: Select all
seq file --> transformer --> dataset
|
reject file
reject file:
col1|col2_notnull|co3_date|col4|col5|Reject_Reason
a1||20110345|data|data|col2_notnull is empty
desire output:
col1|col2_notnull|col3_date|col4|col5|Reject_Reason
a1||20110345|data|data|col2_notnull is empty, col3_date invalid date format
May i know how to concatenate the reject message in transformer stage?
Thanks.
