Warning Message: Cannot preserve partitioning

[adis]

Hi Guys,
Any ideas about the following warning message?

When checking operator: A sequential operator cannot preserve the partitioning of the parallel data set on input port 0.

I am getting this warning message while writing records from transformer to a sequential file. I have been writing to sequential files before also but never got this message.

Thanks!

Select option "Clear" in "Preserver Partitioning" of your transformer output link.

Select option "Clear" in "Preserver Partitioning" of your transformer output link.

Thanks for your quick reply! I will check it.

Do you understand why? Do you understand what this setting does?

Are you even interested?

Hi Ray,

Could you please elaborate the cause? I need your help.

Thnks in advance.

As the default settings are Parallel (Read) and Propagate(write) in a transformer, this becomes a conflict for the sequential file stage which writes in sequential mode while actually receiving them in parallel. By clearing the default mode, we are paving the way acceptable to the seq file.
