[jira] [Created] (HBASE-28015) rpc handler can get stuck on LruBlockCache

 Summary: rpc handler can get stuck on LruBlockCache
 Key: HBASE-28015
 URL: https://issues.apache.org/jira/browse/HBASE-28015
 Project: HBase
  Issue Type: Bug
  Components: BlockCache
Affects Versions: 3.0.0-alpha-4
Reporter: ruanhui
 Fix For: 4.0.0-alpha-1


We found lots of read handlers got stuck on LruBlockCache#getBlock, this may be 
caused by a bug in jdk8 ConcurrentHashMap. To make common fast, I think we'd 
better get and check it before call ConcurrentHashMap#computeIfAbsent.
