[jira] Created: (HIVE-243) ^C breaks out of running query, but not
whole CLI
^C breaks out of running query, but not whole CLI
-------------------------------------------------
Key: HIVE-243
URL: https://issues.apache.org/jira/browse/HIVE-243
Project: Hadoop Hive
Issue Type: Wish
Components: Query Processor
Reporter: Adam Kramer
It would be lovely if, when I know a query is bad, I could just ^C out of it. I can do that now, but the whole CLI quits.
It'd be quite nice if it took an extra ^C to break the CLI, or if there was some control character to break out of a query without breaking out of the CLI.

[jira] Commented: (HIVE-243) ^C breaks out of running query, but

Adam Kramer commented on HIVE-243:
----------------------------------
Specifically, this is an issue because I may or may not have many variables "set" in my CLI instance. I routinely exit out of the CLI via ^C to kill a query, but then end up with (e.g.) the wrong number of reducers selected because it resets to the default.

----------------------------------
Also also, ^C when a query is half-entered should cancel the query in progress and return to the hive> prompt.

Adam Kramer commented on HIVE-243:
----------------------------------
A lot of scripts are currently being used to extend the CLI, for example to allow for tab-completion of table names. These scripts, however, take a long time to run--my version of hive takes about a minute to get me to the CLI. When I hit ^C because I want to stop a query, and the CLI quits, this is actually now a serious performance hit.
