Key: HADOOP-15148
URL: https://issues.apache.org/jira/browse/HADOOP-15148
Project: Hadoop Common
Issue Type: Improvement
Components: common
Affects Versions: 3.0.0
Reporter: BELUGA BEHR
Priority: Trivial
* Use ArrayDeque instead of LinkedList
* Replace an ArrayList that was being used as a queue with ArrayDeque
* Improve write single byte method to hard-code sizes and save time
{quote}
Resizable-array implementation of the Deque interface. Array deques have no
capacity restrictions; they grow as necessary to support usage. They are not
thread-safe; in the absence of external synchronization, they do not support
concurrent access by multiple threads. Null elements are prohibited. This class
is *likely to be* ... *faster than LinkedList when used as a queue.*
