sort funnel and apt_grid_partition
Posted: Mon Oct 17, 2011 9:53 pm
Hi,
I am trying to create a sample job to test sort funnel property in the funnel stage.
1st source file
coulmn1
2
6
4
2nd file
column1
2
3
7
I am expecting data to be sorted in ascending order and my final file should be
2
2
3
4
6
7
But i got in different order. I added a environmental variable $apt_Grid_partitions and set to 1 then i got correct order but if i change it to 4 then i am not getting in ascending order.
My question is what is $apt_Grid_partitions and why is it influencing the outcome?
