             Summary: Saving jdbc interpreter setting takes a long time
                 Key: ZEPPELIN-1223
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1223
             Project: Zeppelin
          Issue Type: Improvement
          Components: Interpreters
    Affects Versions: 0.6.0
            Reporter: Jeff Zhang


I'd like to use hive interpreter, so I make some changes on jdbc interpreter 
and then click the save button. But it takes a long time to finish the saving. 
At first, I thought something wrong with zeppelin, but after checking the log, 
I found it is due to zeppelin is downloading the hive dependencies.  I think it 
would be better to do the dependencies downloading in background, rather than 
hang the saving operation which is not good in user experience.
