> 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 case.
> If the option is not enabled, then we should stick to the current behavior.
> The option can be called: "hive.exec.script.allow.partial.consumption ".
