-----------------------------------
Summary: Avoid closeConnection when openConnection doesn't
finish/succeed
Key: CALCITE-1350
URL: https://issues.apache.org/jira/browse/CALCITE-1350
Project: Calcite
Issue Type: Improvement
Components: avatica
Reporter: Josh Elser
Assignee: Josh Elser
Fix For: avatica-1.9.0
I've noticed during testing of Avatica, often times when SPNEGO authentication
is misconfigured, the client will get stuck in openConnection().
If we consider sqlline and the user control-C's it, sqlline will try to close
the driver as well which would do a closeConnection() (which would also
obviously fail).
I believe we should be able to short-circuit the the closeConnection() when we
know that the openConnection() didn't succeed properly.
Another scenario is when the Avatica server is down. openConnection will fail,
but we'll still attempt the closeConnection on exit.
