Nick Dimiduk updated HBASE-8220:
--------------------------------
Description: 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.
