[jira] [Updated] (HBASE-8220) can we record the count opened HTable for HTablePool

     [ https://issues.apache.org/jira/browse/HBASE-8220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
