Alexey Zabelkin created ZEPPELIN-3712:
-----------------------------------------

             Summary: Add `maxConnLifetime` parameter to JDBC Interpreter
                 Key: ZEPPELIN-3712
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3712
             Project: Zeppelin
          Issue Type: Improvement
    Affects Versions: 0.8.0
            Reporter: Alexey Zabelkin


This parameter is necessary in that case:

1) Zeppelin open connection and keep it in pool;

2) Database close this connection after some time of inactivity;

3) User get an error and necessity to restart interpreter.

 

The default value of this parameter is -1 which means the connection has an infinite lifetime.
