             Summary: Check refCount before free block in BucketCache
                 Key: HBASE-22447
                 URL: https://issues.apache.org/jira/browse/HBASE-22447
             Project: HBase
          Issue Type: Bug
            Reporter: binlijin
            Assignee: binlijin


As discuss in HBASE-22433, the ref count checking within the write lock is 
missing, so may refer to corrupt HFileBlock data with BucketCache.
