Mayank Mishra commented on HAMA-593:
------------------------------------
Yes, I agree with the intend of using a LRU with an upper capacity. But, don't
you think that rather than going with a synchronized+LinkedHashMap, we should
go with LRUCache by extending ConcurrentHashMap, this way as the concurrent
usage increase we should be able to get good performance. Sorry but I didn't
got clues of using just LinkedHashSet for conceptualizing LRU cache.
