Description
In HIVE-24207, an optimization is introduced on task side, where a task can exit quickly if it's needed according to an object cache value, which reflects the current records already pushed through the limit operator.
The AM side optimization will more likely be TEZ-2103 for this scenario.
Early exit can cause uninitialized inputs, that's what this patch is meant to solve.
