--------------------------------------
Summary: 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
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
