guluo updated HBASE-28011:
--------------------------
Description:
LruBlockCache.logStats would print info, as follow:
{code:java}
//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 {code}
I think the description about *totalSize=2.42 MB* is not accurate, It actually
represents the used size of BlockCache.
