>             Project: HBase
>          Issue Type: Bug
>          Components: Client
>    Affects Versions: 0.90.6
>            Reporter: Igor Yurinok
>
> Sometimes we see a lot of Exception about closed connections:
> {code}
>  org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@553fd068 closed
> org.apache.hadoop.hbase.client.ClosedConnectionException: org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@553fd068 closed
> {code}
> After investigation we assumed that it occurs because closed connection returns back into HTablePool. 
> For our opinion best solution is  check whether the table is closed in method HTablePool.putTable and if true don't add it into the queue and release such HTableInterface.
> But unfortunatly right now there are no access to HTable#closed field through HTableInterface
