-----------------------------
Summary: The logStats about LruBlockCache is not accurate
Key: HBASE-28011
URL: https://issues.apache.org/jira/browse/HBASE-28011
Project: HBase
Issue Type: Bug
Components: BlockCache
Affects Versions: 2.4.13
Environment: Centos 7.6
HBase 2.4.13
Reporter: guluo
Assignee: guluo
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.
