Vinay Chella commented on CASSANDRA-14319: ------------------------------------------ Hi Jon, 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 > 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 -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
