I have a project with 3 parts flow [quarterly data, monthly data, "CD" data, as all 3 parts has to go through the same prep we are doing that and stacking it 3 files together, at some point we are splitting it back to in to 3 different flows with split recipe.
It was working just fine last month, suddenly I am re-running quarterly flow and now this split recipe works only for monthly flow, and only monthly table is getting populated and both quarterly and CD is totally empty... Do you have an idea what might caused that?
As you can see on the screen 1 - input table has column "new_dataset" = quarterly, 2 screen it is recipe and 3rd is an output.
Quarterly scenario just ignores that this table is empty, skip all the recipes till the end and it is running to an end as a "success".
Thanks for any suggestions,
This error is indicative of your input dataset is empty. More specifically, you appear to have partitioning enabled for your datasets, and the "quarterly" partition is likely empty. Could you try double-checking your partitioning setup to make sure that it's correct and try rebuilding your impala_result_tab_pq input dataset?

Thanks for your answer. I opened a support ticket with job_diagnosis in it. As this is very strange situation, as I didnt change anything crucial in the flow, and it was working over a month ago. I was trying to re-build impala_result_tab_pq and there was no problem with it, and as you can see on the screen I even filter this dataset by new_dataset=quarterly to check if there is no records for quarterly, but it seems like we have them. And this is the dataset that is just before that split recipe.
