Zeppelin Oracle SQL query runs forewer

问题

I am trying to use Zeppelin (v 0.7.0 java 1.8 on Windows 10; same with docker v .0.7.1) JDBC interpreter to query Oracle Database.

So far I've found papers like example. I try to use jdbc interpreter with:

common.max_count=100
default.driver=oracle.jdbc.pool.OracleDataSource 
default.password:$password
default.user=$my_user_name
default.url=jdbc:oracle:thin:@$host:1521/$service_name>
zeppelin.jdbc.concurrent.max_connection=10
zeppelin.jdbc.concurrent.use=true

Connection looks to be established successfully*, but even simplest query (like sql% select 1 from dual) runs for ever.

Does anyone knows/have a clue on what is to be added?

what I see in terminal - repeating lines

sKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbc DEBUG [2017-06-15 16:03:28,203] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbc DEBUG [2017-06-15 16:03:28,204] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbc DEBUG [2017-06-15 16:03:28,204] ({Thread-90} InterpreterFactory.java[getInterpreterSessionKey]:1244) - Interpreter session key: shared_session, for note: 2CMEC9SS4, user: anonymous, InterpreterSetting Name: jdbc DEBUG [2017-06-15 16:03:28,205] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbc DEBUG [2017-06-15 16:03:28,205] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbc

In the same time I don't have an issue using spark interpretor with scala over jdbc same driver.
