> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Jinglun
> Assignee: Jinglun
> Priority: Major
> Attachments: HDFS-15661.001.patch, HDFS-15661.002.patch,

>
> Currently the DeadNodeDetector is a member of ClientContext. That means it is
> shared by many different DFSClients. When one DFSClient.close() is invoked,
> the DeadNodeDetecotor thread would be interrupted and impact other DFSClients.
> From the original design of HDFS-13571 we could see the DeadNodeDetector is
> supposed to share dead nodes of many input streams from the same client.
> We should move the DeadNodeDetector as a member of DFSClient instead of
> ClientContext.
