We have a problem getting OBIEE (12.2.1.2) to work against our HDP 3.1 environment.   OBIEE run on RHEL 7. We have tried both Hortonworks ODBC Driver for Apache Hive and Clouderas (2.6.4/5). We connect to HDP over Knox on port 8443 and use username och password   We can import metadata from the datasource in OBIEE admin tool. We can via a testtool on Linux connect to Hive using the Hortonworks ODBC Driver   If we try to view data in admin tool, the admin tool kind of crashes and we get no explicit error message. If we try to run a report, we get a general error has occured (HY000) and not so much more. Neither of the two problematic attempts above have resulted in any logs in Knox so it seems like the problem is with OBIEEs usage of the drivers.   Does anyone have a suggestion on how to troubleshoot this issue?   ...
