[GitHub] zeppelin pull request #2923: ZEPPELIN-3312 Add option to convert username to...
GitHub user VipinRathor reopened a pull request: https://github.com/apache/zeppelin/pull/2923 ZEPPELIN-3312 Add option to convert username to lower case ### What is this PR for? This PR introduces a new configuration property to convert username to lower case. This is useful when the users (from external sources like AD/LDAP) are coming in with mixed-case names and Hadoop services (like Hive) can't authorize them correctly because Hadoop services recognize users only in lower case (like Linux). Adding a new config option "zeppelin.username.force.lowercase" to handle such scenarios. Behavior without this PR: Access is denied to CaMel case user while running a Hive paragraph Behavior with this PR: User is allowed to run query when proposed configuration set to true. By default, keeping zeppelin.username.force.lowercase=false to retain the current behavior. ### What type of PR is it? [Bug Fix] ### Todos * [ ] - Unit test ### What is the Jira issue? * https://issues.apache.org/jira/browse/ZEPPELIN-3312 ### How should this be tested? * Travis CI should pass * Manual steps to test: 1. Configure Zeppelin with Active Directory authentication 2. Login to Zeppelin as a CaMel case user 3. Try to run a simple JDBC note with a Hive query (like a select * query). This would fail with "user [CaMel] does not have proper privileges to [USE] operation" error message. 4. Now set zeppelin.username.force.lowercase=true in custom zeppelin-site.xml configuration. 5. Once again, login as CaMel case user. This time the same Hive query would run as expected. Because the username is now passed in lower case. 6. Also notice that after successful login, the login username (in the top-right corner) will be in lower case too. ### Screenshots (if appropriate) * Login as CaMel case user: https://user-images.githubusercontent.com/15668387/38672744-faf00f8e-3e03-11e8-86b2-cc5981d380d2.png";> * Notice the converted username post login: https://user-images.githubusercontent.com/15668387/38672777-108c7b66-3e04-11e8-8c97-467b4b73fe3d.png";> ### Questions: * Does the licenses files need update? No * Is there breaking changes for older versions? No * Does this needs documentation?
