IOException during (re)connection to a controller disconnects all established
connections to this controller
------------------------------------------------------------------------------------------------------------
Key: SEQUOIA-1144
URL: https://forge.continuent.org/jira/browse/SEQUOIA-1144
Project: Sequoia
Type: Bug
Components: JDBC Driver
Reporter: Gilles Rayrat
Assigned to: Gilles Rayrat
When trying to connect, in Driver#connectToNextController(url), if the driver
receives an IOException, it will inform all other connections about its failure
and disconnect them
This intended behavior was a kind of optimization, where the first client
getting an error informs all others so failover is faster.
The drawback is that a transient problem, or an error that doesn't concern all
connections (eg. Too Many Open files) will cancel all other potentially good
connections and make them reconnect.
