>            Reporter: Todd Lipcon

>
> 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.
