Hi Jeff,

Does that mean we can have two Impala interpreters configured? One with 
sequential processing and one with parallel processing?

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?

Right, when zeppelin.jdbc.concurrent.useis false, paragraphs will run as FIFO

Hi Jeff,

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

You can configure zeppelin.jdbc.concurrent.use as false to make jdbc 
interpreter run sequentially

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?
