Hi [~rustyrazorblade],
Are you looking for something like below when we provide invalid datacenter as
an option to rebuild?
{code:java}
$ bin/nodetool rebuild no_dc
nodetool: Provided datacenter: no_dc is not a valid datacenter, available
datacenters are: datacenter1, datacenter2
See 'nodetool help' or 'nodetool help <command>'.
$
{code}
And for
{quote}3. Ideally, we indicate which keyspaces are set to replicate to this DC
and which aren't
{quote}
Are you referring {{this}} as the datacenter from where the {{rebuild}} command
is being executed from or the one which is provided as an option (e.g.,
{{no_dc}} in above example)? if it is the later, invalid dc would not have any
keyspaces, so what is expected for #3 in this scenario?
I am interested in working on this ticket. Can you assign this ticket to me?

> nodetool rebuild from DC lets you pass invalid datacenters

> Key: CASSANDRA-14319
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14319
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Jon Haddad
> Assignee: Vinay Chella
> Priority: Major
> Fix For: 2.1.x, 2.2.x, 3.0.x, 3.11.x, 4.x
>
>
> If you pass an invalid datacenter to nodetool rebuild, you'll get an error
> like this:
> {code}
> Unable to find sufficient sources for streaming range
> (3074457345618258602,-9223372036854775808] in keyspace system_distributed
> {code}
> Unfortunately, this is a rabbit hole of frustration if you are using caps for
> your DC names and you pass in a lowercase DC name, or you just typo the DC.
> Let's do the following:
> # Check the DC name that's passed in against the list of DCs we know about
> # If we don't find it, let's output a reasonable error, and list all the DCs
> someone could put in.
> # Ideally we indicate which keyspaces are set to replicate to this DC and
> which aren't
