>                 URL: https://issues.apache.org/jira/browse/HBASE-8220
>             Project: HBase
>          Issue Type: Improvement
>          Components: Client
>    Affects Versions: 0.94.3
>         Environment: In HTablePool, we have a method getCurrentPoolSize(...) to get how
many opened HTable has been pooled. However, we don't know ConcurrentOpenedHTable which means
the count of HTable get from HTablePool.getTable(...) and don't return to HTablePool by PooledTable.close().
The ConcurrentOpenedHTable may be meaningful because it indicates how many HTables should
be opened for the application which may help us set the appropriate MaxSize of HTablePool.
Therefore, we can and a ConcurrentOpenedHTable as a counter in HTablePool.
