how to write a UDF which when encountered it should stop the map

[Former Member]

hi all,

My task is to write a UDF which when encountered it should stop the map and return what is given as an input to the UDF For ex: UDF(map failed!)

when this udf is encountered than the map should stop and the output output should be mapfailed!

Hi Bhargav,

i think the whole mapping is stopped. You ll get an exception. Look to the screenshot at the bottom.

BTW: Allesandros blogs are magic..

UDFs r used in graphical mappings and the details in blog shows that when a UDF stops a mapping, it in turn stops whole messgae mapping. So ur entire Mapping process would get stopped
