Zhe Zhang commented on HDFS-8808:
---------------------------------
Thanks [~ggop] for reporting the problem.
[~ajithshetty]: I think your idea is a valid workaround. However I think we
still need a proper fix to address the issue. Changing system configuration
only for a specific operation incurs more burden to admins and is prone to
human errors.
I'll take a crack on the task.

>
> The parameter {{dfs.image.transfer.bandwidthPerSec}} can be used to limit the
> speed with which the fsimage is copied between the namenodes during regular
> use. However, as a side effect, this also limits transfers when the
> {{-bootstrapStandby}} option is used. This option is often used during
> upgrades and could potentially slow down the entire workflow. The request
> here is to ensure {{-bootstrapStandby}} is unaffected by this bandwidth
> setting
