Hi DSXians,
I am getting the following warning for a Sort which is palce in front of a aggregator.
"AGG020: When checking operator: User inserted sort "SRT010" does not fulfill the sort requirements of the downstream operator "APT_SortedGroup2Operator in AGG020""
Since aggregator requrie a sorted input, i introduce a sort.
And also let me know what is better, Explicit sort or implicit sort.
I guess it is explicit sort right??
regards
kumar

Read the message again. Read the whole message.
It's not about implicit or explicit. It's not about Sort stage versus sort specified on a stage's input link.
The message tells you that the sort that you specified is in some way incompatible with the requirements of a downstream operator. You can find that operator by viewing the generated OSH.

Thanks Jayant,jayantthakore wrote:Hi,
Are you changing the name of the Sort key Column and then using it for Aggregation?
You might get this warning if the Sort and Aggregating keys are different or are not in same order.
Thanks

I too looked upon these issues before posting.
Ray,
you made me to explore in to OSH, Though i couldnt get much information from that, the setup of the job was follows
Code: Select all
seq file010---->Sort020--->Aggregator030 seq file080
| |
| |
merge060------- lookup070----seqfile090
|
seq file040-------------Sort050-------
THE WARNING VANISHES.
But, just to know the reason, when i revoked the change i make, i could not get the previous warning
regards
