> Remove {{LinkedList}} in favor of {{ArrayList}} for class
> {{org.apache.hadoop.hive.metastore.HiveAlterHandler}}.
> {quote}
> The size, isEmpty, get, set, iterator, and listIterator operations run in
> constant time. The add operation runs in amortized constant time, that is,
> adding n elements requires O(n) time. All of the other operations run in
> linear time (roughly speaking). *The constant factor is low compared to that
> for the LinkedList implementation.*
