Hi Aswin,
You can always try "Dont combine" option.
Still more infromatin needed from you side.

Thanks .

But Changing the combinability mode also doesn't help.


What infomation you need?
Abt the job. It reads a sequential file, does some transformations on it . Then there is a join with a master file. Which is of zero byte for the first run. Join is full outer. After that there is a transformer in which we are doing null handling and finally writing the output to a sequential file.


Please let me know if this can help you solve my problem.

Thanks
Ashwin

Hummm.... bit tough.....
Try to concentrate on transformations in the transformer stage, try to make use of modify stage for null handling...
Though it is not helping you directly, it may be usefull to narrow down the point of error.

Hi,
As this is a clear follow up for the previous post please post a reply rather then a new post for the same issue.

I'll add the original question to this post and remove the original post.

Can you set APT_DISABLE_COMBINATION=True and run the job again as kumar suggested? It would at least show you where the error is coming from (which operator). Also, how are you handling the nulls that are getting inserted from the join?
