Daniel Barclay (Drill) commented on DRILL-2628: ----------------------------------------------- If DRILL-2628 is because a connection gets closed but still used, then the hanging part will be fixed by the fix for DRILL-2565. (There should be an exception rather than just a hang.) > sqlline hangs and then asserts when trying to execute anything on a dead JDBC > connection > ---------------------------------------------------------------------------------------- > > Key: DRILL-2628 > URL: https://issues.apache.org/jira/browse/DRILL-2628 > Project: Apache Drill > Issue Type: Bug > Components: Client - JDBC > Affects Versions: 0.8.0 > Reporter: Victoria Markman > Assignee: Daniel Barclay (Drill) > > Here is what I'm observing: > 1. Start drill > 2. Start sqlline > 3. Run couple of queries > 4. Bounce drill > 5.
