Hi, Anyone know
Where istimeout configuration for JDBCconnection for Hive and Impala which is truly apply on RapidMinerStudioand RapidMinerAI hub Server?

There are the steps in more details below that I have applied but it does not truly eliminate the timeout issue:

1. I am using JDBC Impala and Hive connection from JDBC driver jar. with RapidMiner 9.8

Both connections are test successful.

2. I set my timeout RapidMiner studio > Settings> Preferences > Tools >Database Login timeout

3. I ran verysimple flow(to retrieve one table), it works fine as shown below (unit of time = millisecond)

4. However, I ran morecomplex workflowonRapidMiner Studioand took around 12 minutes. Then, it threw timeout exception. Sometime, I ran the same workflow on RapidMiner studio, it ran successfully.

5. Moreover, I tried thecomplex workflowonRapidMiner AI hub Server, It took around 3 minutes and threw timeout exception.

Thanks
