Subject [jira] Commented: (HIVE-869) Allow ScriptOperator to consume not all input data
Date Fri, 09 Oct 2009 07:55:31 GMT


Venky Iyer commented on HIVE-869:

Reading the patch very cursorily made it seem as if we weren't checking the exit status of
the script. Checking that the exit code was 0 is absolutely essential, or we'll mask real

If we're actually checking that the script exists with success, then it seems like the option
is misnamed- should be more like


or something like that.

> The ScriptOperator (SELECT TRANSFORM(a, b, c) USING 'myscript' AS (d, e, f) ...) has
a problem:
> If the user script exits without consuming all data from standard input, then we will
report an error even if the exit code from the user script is 0.
> We want to have an option, when enabled, ScriptOperator will return successfully in that
> If the option is not enabled, then we should stick to the current behavior.
> The option can be called: "hive.script.ignore.broken.pipe.exception".
