> Key: HDFS-3646
> URL: https://issues.apache.org/jira/browse/HDFS-3646
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs client
> Affects Versions: 0.23.3, 2.0.0-alpha
> Reporter: Kihwal Lee
> Assignee: Kihwal Lee
> Priority: Critical
> Fix For: 3.0.0, 2.2.0-alpha
>
> Attachments: hdfs-3646.patch, hdfs-3646.patch.txt, hdfs-3646.patch.txt
>
>
> If {{LeaseRenewer#closeClient()}} is not called, {{LeaseRenewer}} keeps the
> reference to a {{DFSClient}} instance in {{dfsclients}} forever. This
> prevents {{DFSClient}}, {{LeaseRenewer}}, conf, etc. from being garbage
> collected, leading to memory leak.
> {{LeaseRenewer}} should remove the reference after some delay, if a
> {{DFSClient}} instance no longer has active streams.
