Hi all,
For those DS experts out there, I am facing an interesting issue which you may have come across. although i am assuming you may think this is a typical SIGSEGV problem (which i am not too sure about).
Job Background:
Input: a dataset (sequential execution mode)
reference dataset (sequential execution mode)
Process: lookup (parallel execution mode)
Output: oracle table (sequential execution mode)
Issue: everything works as described above, but if i change the lookup stage excution mode from parallel to sequential, the job abort with SIGSEGV error: Operator terminated abnormally: received signal SIGSEGV. Please explain. Thanks.
DS Lookup issue, an interesting one!

Sequential is still parallel (one-way parallel). The Lookup stage should be able to handle it. Have you constrained the Lookup stage to operate in sequential mode also?
