I don't think using an array will work well for a map key. The hashCode() and equals() functions for an array come from Object and therefore do not consider the array elements. Could use `List<String>` as the key and construct the list using Arrays.asList(options) which efficiently wraps an array. List created in this way have hashCode() and equals() based on the list elements.
Could use a Guava cache instead instead of using a ConcurrentHashMap . Then the cache could be configured with an age. [ Full content available at: https://github.com/apache/accumulo/pull/645 ] This message was relayed via gitbox.apache.org for [email protected]
