It is per interpreter. You can create impala interperter based on jdbc template. and configure its zeppelin.jdbc.concurrent.use to false,

Jeff, OK makes sense. Is this a global setting? Can it be set per user, or per Notebook?

Hi Jeff, Thank you for the reply. So that will result in Impala paragraphs running sequentially? Is that because Impala goes through JDBC?

I am using Zeppelin 0.8.0-SNAPSHOT with Impala. If I understand correctly, paragraphs that use the same interpreter should process sequentially. But some of the paragraphs seem to process in parallel. Am I wrong that they should be sequentially executed, or is there something different about Impala? Is there some configuration option I can check? Chris
