> [Java] Implement quick sort in a non-recursive way to avoid stack overflow

> Key: ARROW-6732
> URL: https://issues.apache.org/jira/browse/ARROW-6732
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Java
> Reporter: Liya Fan

> The current quick sort algorithm in implemented by a recursive algorithm. The
> problem is that for the worst case, the number of recursive layers is equal
> to the length of the vector. For large vectors, this will cause stack
> overflow.
> To solve this problem, we implement the quick sort algorithm as a
> non-recursive algorithm.
