---------------------------------------
[~ahussein] Thanks. Btw I was wondering if we really need a new wrapper.
Perhaps we can directly replace them with "new ArrayList<>()" ?

> guava Lists class provide some wrappers to java ArrayList and LinkedList.
> Replacing the method calls throughout the code can be invasive because guava
> offers some APIs that do not exist in java util. This Jira is the task of
> implementing those missing APIs in hadoop common in a step toward getting rid
> of guava.
> * create a wrapper class org.apache.hadoop.util.unguava.Lists
> * implement the following interfaces in Lists:
> ** public static <E> ArrayList<E> newArrayList()
> ** public static <E> ArrayList<E> newArrayList(E... elements)
> ** public static <E> ArrayList<E> newArrayList(Iterable<? extends E>
> elements)
> ** public static <E> ArrayList<E> newArrayList(Iterator<? extends E>
> elements)
> ** public static <E> ArrayList<E> newArrayListWithCapacity(int
> initialArraySize)
> ** public static <E> LinkedList<E> newLinkedList()
> ** public static <E> LinkedList<E> newLinkedList(Iterable<? extends E>
> elements)
> ** public static <E> List<E> asList(@Nullable E first, E[] rest)
