> Key: HADOOP-8202
> URL: https://issues.apache.org/jira/browse/HADOOP-8202
> Project: Hadoop Common
> Issue Type: Bug
> Components: ipc
> Affects Versions: 0.24.0
> Reporter: Hari Mankude
> Assignee: Hari Mankude
> Priority: Minor
> Attachments: HADOOP-8202.patch, HADOOP-8202.patch
>
>
> I was running testbackupnode and noticed that NNprotocol proxy was not being
> closed. Talked with Suresh and he observed that most of the protocols do not
> implement ProtocolTranslator and hence the logic in stopproxy() does not
> work. Instead, since all of them are closeable, Suresh suggested that
> closeable property should be used at close.
