> Currently if a regionserver is aborted due to fatal error or stopped by
> operator on purpose, it will be added into {{ServerManager#deadservers}} list
> and shown as "Dead Servers" in the master UI. This is a valid warn for
> operators to notice the self-aborted servers and give a sanity check to
> avoid further issues. However, after necessary checks, even if operator is
> sure that the node is decommissioned (such as for repair), there's no way to
> clear the dead server list except restarting master. See more details in
> [this

> Here we propose to add a hbase shell command to allow clearing dead server
> list in {{ServerManager}} for advanced users, and the command should be
> executed with caution.
