Allan Yang commented on HBASE-21392:
------------------------------------
As for me, I don't think it is a big problem. If the Table is created from the
Connection, the HTable won't hold any resources like thread pool, so we do not
need to close the HTable(Or close the HTable takes no effect). But if we close
the underlying Connection(or close a HTable who create a connection inside, not
recommend, of course), it will throw an Exception.
> HTable can still write data after calling the close method.

> HTable can still write data after calling the close method.
>
> {code:java}
> val conn = ConnectionFactory.createConnection(conf)
> var table = conn.getTable(TableName.valueOf(tableName))
> val put = new Put(rowKey.getBytes())
> put.addColumn("cf".getBytes(), columnField.getBytes(), endTimeLong,
> Bytes.toBytes(line.getLong(8)))
> table.put(put)
> //call table close() method
> table.close()
> //put again
> val put1 = new Put(rowKey4.getBytes())
> out1.addColumn("cf".getBytes(), columnField.getBytes(), endTimeLong,
> Bytes.toBytes(line.getLong(8)))
> table.put(put1)
> {code}
>
> after call close method ,can alse write data into HBase,I think this does not
> match close logic.
