`numPartitions` might be not a good name for this purpose. How about 
`maxConnections`?

Thank you for review, @lichenglin .

For 1, Jenkins test that, too.
For 2, sure! It sounds reasonable and better.

https://github.com/apache/spark/pull/15868
  
I'm sorry,my network is too bad to download dependencies from maven rep for 
building spark.
I have seen your PR and here is some suggestions:

1. I notice the PR has used CaseInsensitiveMap,becasuse "numPartitions" is 
still used by DataframeReader,we'd better to check whether jdbcreading work 
well.

2."Testing the Total Connections" may be difficulty,because when the tasks 
finish the connection will be closed.I have better way to check the  
numPartitions if works, we can watch the last stage's task on spark ui,there 
should be "numPartitions" task in the last step.
