> With off-heap/bucketCache being used to cache data blocks without going through on-heap
cache, the logic used in lruCache to check the content of already cached block need to be
included in bucketCache. Please see this [discussion|https://mail-archives.apache.org/mod_mbox/hbase-dev/201708.mbox/%3cCAO40JLCnXLw3=0bbUaXdDx=w2fkLLJefVgJ6-UVJ_2JhfvOz+Q@mail.gmail.com%3e]
for details.
