Hi, Regarding java.lang.ClassNotFoundException: org.apache.hadoop.security. UserGroupInformation$AuthenticationMethod error, I assume you're using master branch. (0.6.x branch shouldn't have this error) You can add "org.apache.hadoop:hadoop-common:2.7.2" in the Dependencies section of your interpreter setting on GUI, to remove this error.
If you want to put your custom driver, you can set path of your jar in the local filesystem, in the Dependencies section of your interpreter setting, instead of "mysql:mysql-connector-java:5.1.38".
