> HBASE-4893 is related to this issue. In that issue, we know, if multi-threads share a same connection, once this connection got abort in one thread, the other threads will got a "HConnectionManager$HConnectionImplementation@18fb1f7 closed" exception.
> It solve the problem of "stale connection can't removed". But the orignal HTable instance cann't be continue to use. The connection in HTable should be recreated.
> Actually, there's two aproach to solve this:
> 1. In user code, once catch an IOE, close connection and re-create HTable instance. We can use this as a workaround.
> 2. In HBase Client side, catch this exception, and re-create connection.
