Description

Prerequisites:

1. Drill with the JDBC driver is built with "mapr" profile
2. Security is enabled and PLAIN authentication is configured

Steps:

1. Use some external JDBC client to connect (e.g. DBeaver)
2. Connection string: "jdbc:drill:drillbit=node1:31010"
3. Set appropriate user/password
4. Test Connection

Expected result:
Connection successful.

Actual result:
Exception happens:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
