--------------------------------------
Summary: Using CTRL-C to cancel a query and exit SQLLINE cancels
query but causes SQLLINE shell to hang
Key: DRILL-1378
URL: https://issues.apache.org/jira/browse/DRILL-1378
Project: Apache Drill
Issue Type: Bug
Components: Client - CLI
Affects Versions: 0.4.0
Environment: MapR v3.1.1, RHEL 6.5
Reporter: Michael England
When running a query (in this case a Drill query over a large Hive table),
pressing CTRL+C to cancel a query and exit the shell causes a cancellation
message in sqlline.log but causes the SQLLINE shell to hang. CTRL-Z then needs
to be pressed and the SQLLINE process needs to be killed manually. A CTRL+C
keyboard interrupt should cancel the query and provide a new empty query line
in the shell. A further CTRL-C keyboard press should exit the SQLLINE shell.
sqlline.log cancellation entry:
