    Description

      LruBlockCache.logStats would print info, as follow:

      //代码占位符
INFO  [LruBlockCacheStatsExecutor] hfile.LruBlockCache: totalSize=2.42 MB, freeSize=3.20 GB, max=3.20 GB, blockCount=14, accesses=31200, hits=31164, hitRatio=99.88%, , cachingAccesses=31179, cachingHits=31156, cachingHitsRatio=99.93%, evictions=426355, evicted=0, evictedPerRun=0.0

      I think the description about totalSize=2.42 MB is not accurate, It actually represents the used size of BlockCache.
