Anoop Sam John created HBASE-16651: -------------------------------------- Summary: LRUBlockCache#returnBlock should try return block to Victim Handler L2 cache. Key: HBASE-16651 URL: https://issues.apache.org/jira/browse/HBASE-16651 Project: HBase Issue Type: Sub-task Affects Versions: 2.0.0 Reporter: Anoop Sam John Assignee: Anoop Sam John Fix For: 2.0.0
In case of L1 and L2 cache usage with combinedMode = false, L2 is used as a victim handler cache for L1 cache. When a getBlock() request comes, L1 will see if block is in it and if not it will try to provide the block from L2 cache. In such a case, the return block must return the block to L2 cache and count down the ref count for the block. But right now we just ignore the returnBlock call in LRUCache -- This message was sent by Atlassian JIRA (v6.3.4#6332)
