Re: Sequential processing disabled?

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

Subject: Sequential processing disabled?

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?

Right, actually you can create as many impala interpreter as you can. And each impala can have different setting.

Hi Jeff,

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