Weiqing Yang commented on HBASE-17047:
--------------------------------------
Sorry for the misleading title/description. Our client has asked us to log
information about the cache, but we’ve decide not to do so. It’s an API that
gives statistics information of the cache (like you suggested). The refcount
has nothing to do with this patch, but its decrement is here:
