Daryn Sharp commented on HDFS-8690:
-----------------------------------
I see HDFS-7314 is trying to address the same problem but appears stalled. It
looks like a better fix. Can we expedite HDFS-7314? If not, this jira is a
tiny step in the right direction. Chang filed this after I analyzed a
production incident that required oozie and other services to be restarted
because the renewer aborted the client.
> LeaseRenewer should not abort DFSClient when renew fails

> Key: HDFS-8690
> URL: https://issues.apache.org/jira/browse/HDFS-8690
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Reporter: Chang Li
> Assignee: Chang Li
> Attachments: HDFS-8690.1.patch
>
>
> The lease renewer special cases SocketTimeoutExceptions to abort the
> DFSClient. Aborting causes the client to be permanently unusable, which
> causes filesystem instances to stop working. All other IOExceptions do not
> abort. The special case should be removed and/or abort should not completely
> shutdown the proxy.
