I have worked with the following combinations and not had an issue. ODBC v1.3.16 - you may want to consider upgrading to it.
Apache Drill on MapR v 1.10, 1.11 & 1.12 (just did a little with 1.13 but not had issues). All the Drill storage plugins are healthy and working properly. All the Drill Views are well defined and working properly. You can do a quick test by running "show schemas" to see if it is responsive and returns the results quickly. Tableau 10.2, 10.5 and 2018.1 using the Apache Drill data connection. All of them work fine in my case with the above Drill versions and ODBC driver mentioned. Make sure nothing got flaky in you Drill env. I did a quick guide for Drill with BI Tools that has been helpful for many users. https://community.mapr.com/community/exchange/blog/2017/01/25/drill-best-practices-for-bi-and-analytical-tools --Andries On 5/15/18, 9:22 PM, "Divya Gehlot" <divya.htco...@gmail.com> wrote: Hi, I am facing tableau and Apache Drill connectivity issue recently , which was all working fine for long time (for more than 9+ months ) I did tested couple of scenarios, sharing below : *Driver Version* - MapR Driver Version 1.3.0 *Scenario 1 : Tableau 10.2 - Apche Drill Connection - handshake timeout 180 in system dsn* *Error :* The connection to the data source might have been lost.
