> Key: HDFS-4176
> URL: https://issues.apache.org/jira/browse/HDFS-4176
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ha, namenode
> Affects Versions: 2.0.2-alpha, 3.0.0-alpha1
> Reporter: Todd Lipcon
> Assignee: Lei (Eddy) Xu
> Attachments: HDFS-4176.00.patch, HDFS-4176.01.patch,
> HDFS-4176.02.patch, HDFS-4176.03.patch, HDFS-4176.04.patch, namenode.jstack4
>
>
> When the EditLogTailer thread calls rollEdits() on the active NN via RPC, it
> currently does so without a timeout. So, if the active NN has frozen (but not
> actually crashed), this call can hang forever. This can then potentially
> prevent the standby from becoming active.
> This may actually considered a side effect of HADOOP-6762 -- if the RPC were
> interruptible, that would also fix the issue.
