Thu Nov 10 00:25:35 2016  zznate:aweisberg if you wanted to throw in CASSANDRA-8751 w. 7544 for funzies, that would be dope!
Thu Nov 10 00:25:36 2016  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-8751 (Open; Unresolved; 3.x): "C* should always listen to both ssl/non-ssl ports"

Thu Nov 10 00:47:07 2016  jasobrown:zznate: that should probably be on me, for the work i'm doing on #8457
Thu Nov 10 00:47:09 2016  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-8457 (Patch Available; Unresolved; 4.x): "nio MessagingService"
Thu Nov 10 00:47:19 2016  jasobrown:actually, that might be a dupe of #10404, already assigned to me
Thu Nov 10 00:47:19 2016  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-10404 (Open; Unresolved; Unscheduled): "Node to Node encryption transitional mode"
Thu Nov 10 00:47:53 2016  zznate:8751 is what i had in my notes, dont think ive seen 10404
Thu Nov 10 00:48:19 2016  jasobrown:yeah, looks like they are dupes
Thu Nov 10 00:48:29 2016  zznate:but yeah, taking transitional SSL would be rad
Thu Nov 10 00:48:44 2016  zznate:+1 on the dupes
Thu Nov 10 00:48:51 2016  zznate:close/dupe as you see fit
Thu Nov 10 00:49:05 2016  jasobrown:ahh, i see - it's not strictly dupes, but i think 10404 is more interesting ;)
Thu Nov 10 00:49:22 2016  jasobrown:i was planning on getting to it after 8457
Thu Nov 10 00:49:45 2016  jasobrown:wdyt?
Thu Nov 10 00:49:52 2016  jasobrown:ahh, ok ;)
Thu Nov 10 00:51:38 2016  zznate:i kinda see 10404 as a side effect of 8751?
Thu Nov 10 00:51:45 2016  aweisberg:zznate: That sounds like it should be pretty easy. Maybe finicky for people who are not expecting two ports to be bound.
Thu Nov 10 00:52:16 2016  jasobrown:yeah, i think we should just support StartTLS (trasitional SSL) on the single port
Thu Nov 10 00:52:56 2016  aweisberg:How would that work against older versions that don't support StartTLS?
Thu Nov 10 00:53:08 2016  zznate:just so long as we are on the same page of 'i have vnodes and want to switch to SSL on storage port w/o downtime'
Thu Nov 10 00:53:25 2016  jasobrown:zznate: +1, that's the idea
Thu Nov 10 00:53:58 2016  zznate:user list gets asked that about 1x every other week or so
Thu Nov 10 00:54:48 2016  jasobrown:aweisberg: i guess my thought on it is "wait until you've upgraded the entire to enable it"?
Thu Nov 10 00:55:07 2016  jasobrown:which i guess is kinda the case in both tickets
Thu Nov 10 00:55:30 2016  zznate:krut - are your folks SSL out of the gate or do you have to transition to that on occasion?
Thu Nov 10 00:55:55 2016  jasobrown:zz
Thu Nov 10 00:56:23 2016  jasobrown:zznate: gotta run, but will check in on this convo later - or if you want to move it to a ticket that's be swell too
Thu Nov 10 00:56:56 2016  aweisberg:I am also leaning towards not doing #1159. It really looks like it expands the scope for an orthogonal improvement. It impacts operations like replacing a node that don't have to be impacted.
Thu Nov 10 00:56:56 2016  zznate:thanks - appreciate it!
Thu Nov 10 00:56:58 2016  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-1159 (Resolved; Duplicate; Unscheduled): "For contrib modules that use Java, have a consistent build mechanism"
Thu Nov 10 00:57:13 2016  zznate:^hahaahahaha. i actually remember that one!
Thu Nov 10 00:58:00 2016  zznate:CASSANDRA-11559
Thu Nov 10 00:58:01 2016  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-11559 (Open; Unresolved; Unscheduled): "Enhance node representation"
Thu Nov 10 01:00:56 2016  zznate:interesting idea, but that is some surgery.
Thu Nov 10 01:01:50 2016  zznate:CASSANDRA-9244 is kind of edge-case-y
Thu Nov 10 01:01:51 2016  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-9244 (Open; Unresolved; 2.1.x, 2.2.x, 3.0.x, 3.x): "replace_address is not topology-aware"
Thu Nov 10 01:02:47 2016  zznate:... actually, this might become more of an issue for container/mesos/etc folks
Thu Nov 10 01:04:06 2016  zznate:jeffj (or other my cluster is F*ing massive ppl) is 9244 an issue for you?
Thu Nov 10 01:04:58 2016  zznate:dikang ^
Thu Nov 10 01:07:39 2016  jeffj:why would you change topology with replace_address?
Thu Nov 10 01:07:47 2016  jeffj:that sounds like a misuse of the functionality
Thu Nov 10 01:08:12 2016  jeffj:"you wanted to replace a node over there with a node over here. it has different ownership. so we're replacing it in name only, because it's getting totally different data"
Thu Nov 10 01:14:01 2016  zznate:mesos resource offer is only thing i can really think of
Thu Nov 10 01:14:23 2016  zznate:^you got bigger issues if you are there now, imo

Thu Nov 10 01:50:18 2016  dikang:@zznate it's not a big issue for us now, we built some tools around that.
Thu Nov 10 01:51:06 2016  zznate:ok cool. thx
Thu Nov 10 01:57:33 2016  krut:zznate: new clusters are SSL out of the gate, however we do migrate a lot of customers which may not have encryption turned on and thus don't have it turned on post-migration. the node to node encryption transitional mode would be a big win
Thu Nov 10 01:58:00 2016  zznate:^agreed
Thu Nov 10 01:58:05 2016  zznate:thx!
Thu Nov 10 01:59:23 2016  krut:when i say "may not" i actually mean "every single migration we've ever done the customer isn't using encryption" as well. i have a strong feeling it's one of those "oh we didn't enable that initially and now it's too late" options for a lot of users.

Thu Nov 10 16:40:28 2016  paulomotta:I agree #9244 is edge-casey enough to not justify #11559, but that may simplify/enable other things like incremental bootstrap #8494 and #12344

Thu Nov 10 16:42:19 2016  paulomotta:the idea is to have a "enabled_for_reads" flag per token - which can be disabled when the node is being replaced, or enabled when a bootstrapping node is ready to serve reads of particular range
Thu Nov 10 16:45:23 2016  paulomotta:and spread this via gossip as well ofc

Thu Nov 10 23:17:06 2016  krut:so we had a user drop a column and then add it back with a different type, which totally broke their cluster. it seems to me like cassandra should stop people from doing this, or at least handle it in a way that doesn't cause everything to fall apart. what do people think?
