             Summary: Replace the O(N) freeBufferCount by usedBufferCount in 
ByteBuffAllocator metrics
                 Key: HBASE-22412
                 URL: https://issues.apache.org/jira/browse/HBASE-22412
             Project: HBase
          Issue Type: Sub-task
            Reporter: Zheng Hu
            Assignee: Zheng Hu


Address the comment in HBASE-22387: 
bq. The ByteBuffAllocator#getFreeBufferCount will be O(N) complexity, because 
the buffers here is an ConcurrentLinkedQueue. It's worth file an issue for this.
