"RapidMinerServer and Postgresql in AWS"
I have a weird problem with RapidMiner server and Postgresql hosted in AWS. Basically , sometimes processes fail to fetch/read data from a postgresql database giving the error:
SEVERE: Process failed: com.rapidminer.operator.UserError: Cannot retrieve repository data from entry '//DB/advancedanalytics/Example Sets/analytics_data.conditions'. Reason: Requested repository DB does not exist..
The trouble is if I ran the same process on RapidMiner studio, it executes successfully and at some point the problem would clear by itself on RapidMiner server.
Is there a known problem on RapidMiner server and postgresql connectivity?
