--------------------------------------
Summary: Add an option to covert username to lower case
Key: ZEPPELIN-3312
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3312
Project: Zeppelin
Issue Type: Bug
Components: zeppelin-server
Affects Versions: 0.7.4
Reporter: Vipin Rathor
Assignee: Vipin Rathor
Zeppelin, when configured with external authentication system, can have
username in various cases (either UPPER case, lower case or even CaMel case).
On the other side, the Hadoop services expect username to be in lower case.
Problem arises when end users are logging in with upper/camel case username and
Hadoop services (such as Hive) can't authorize them.
Proposing a new option in Zeppelin - "zeppelin.username.force.lowercase" to
handle such scenarios.
Current Behavior:
Access is denied to CaMel case user while running a Hive paragraph
Expected Behavior:
User should be allowed to run query with proposed configuration set to true.
By default, keeping zeppelin.username.force.lowercase=false to retain the
current behavior.
