----------------------------------------
just add comments for dangerous methods ! I am happy if this is fixed since it
is PIA othwerise when it is unpredictable.
> Sqoop2: Guard test DerbyProvider from infinite waits in Derby implementation

> This is pretty much follow up on SQOOP-1816 where I was facing situation that
> calling {{DriverManager.getConnection()}} for {{DerbyProvider}} would wait
> forever in case that Derby server failed to start. I've solved that in
> SQOOP-1816 by adding explicit call to {{ping()}} method that is suppose to
> throw an exception in case that the server is not available. At that time it
> solved my issue, but now the problem is back and I'm observing similar
> infinite wait inside the {{ping()}} call itself.
> I'm not sure what exactly is going wrong with on machine, but it's making the
> tests very unreliable. I've tried to google about the problem, but without
> much luck and hence I would like to propose to make the {{DerbyProvider}}
> smarter and prevent the infinite wait by calling certain "dangerous" methods
> with explicit timeout.
