Prevent the compaction read requests from changing the hotness of block cache
-----------------------------------------------------------------------------
Key: HBASE-5383
URL: https://issues.apache.org/jira/browse/HBASE-5383
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
Assignee: Liyin Tang
Block cache is organized in an sorted way based on LRU or some other algorithm
and it will age out some blocks when the algorithm believes these blocks are
not hot any more.
The motivation here is to prevent the compaction read requests from changing
the hotness of block cache.
