I had set diffent unterpreteters:
mysql, psql, python.
I create a connection to PSQL, unload data and agregate them to calculate the end report. Then z.show(report).
The path is similar. I generate SQL expression with group aggregation.
I only load report data without any aggregation.
I was trying all operations independently and separetly with cron expressions, but the result was the same.
First time, Cron worked excellently, but it was out of order (through 2 hours to 1,5 days). It looks like the paragraphs will not run. There aren't errors in interpreteters and zeppelin logs.
In handle mode i can update all paragraphs
