nabacg commented on SPARK-12312: -------------------------------- My suggestion was for people who need a working solution now and can't wait till there is a new Spark release out and/or can't easily upgrade their cluster installations (which happens in corporate multi-tenant situations, I've been there.. ). My approach avoids those problems by patching the JDBC driver, instead of Spark. It's not a long term solution, but perhaps will save someone some skin. I certainly worked for me and one of my clients. > JDBC connection to Kerberos secured databases fails on remote executors > ----------------------------------------------------------------------- > > Key: SPARK-12312 > URL: https://issues.apache.org/jira/browse/SPARK-12312 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.5.2, 2.4.2 > Reporter: nabacg > Priority: Minor > > When loading DataFrames from JDBC datasource with Kerberos authentication, > remote executors (yarn-client/cluster etc. modes) fail to establish a > connection due to lack of Kerberos ticket or ability to generate it. > This is a real issue when trying to ingest data from kerberized data sources > (SQL Server, Oracle) in enterprise environment where exposing simple > authentication access is not an option due to IT policy issues. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
