tellesnobregaelmiko, what is the problema that you see in making the folder name zookeeper?13:52
*** zhidong has joined #openstack-sahara13:53
elmikotellesnobrega: no problem specifically, i just thought creating a symlink would support the behavior of the storm plugin while still maintaining the original zk directory.13:53

tellesnobregaelmiko, I see. So just leave the folder as it is and link zookeeper -> zookeeper-3.4.613:56
tellesnobregaelmiko, sounds great13:56
tellesnobregawill do in a bit13:56
elmikotellesnobrega: right, instead of doing the tar into a zk dir, just extract the tar and then make a zookeeper symlink. i think the new storm change will work, and we can keep backward compat(if it's even an issue).13:59

egaffordSergeyLukjanov: To clarify my role, by the way (as it came up in the meeting): I am full-time on Sahara, but since I started in November I've been tasked pretty heavily with internal RH tasks around launch of our first fully supported version of Sahara. That launched (quite) recently, though, so I'm now committed to Sahara fully (though I may do integrations as well from time to time, as with TripleO.) But yes, the basic me14:40
SergeyLukjanovegafford, cool, thx for the clarification!14:41

egaffordtosky: Yeah, I use a graphical client (Pidgin), and sometimes I go long and it doesn't work for some receivers. Thanks for the check. "The basic me" would be an odd way to end that.14:43

egaffordHave we ever talked about having an automatic, small number of rechecks on individual failing CI jobs? I understand that the goal absolutely should be to improve reliability of the tests, but at present it seems like we very frequently recheck multiple times until the whole set happens to work at once.18:53
egaffordI can't imagine the cluster is too happy about all the extra workload.18:54

vgridnev_Which issues with rechecks?20:02
*** Longgeek has quit IRC20:02
egaffordvgridnev_: We very often recheck CI jobs multiple times on a commit. This uses a lot of CI cluster time, and generally slows us down. One solution people sometimes use in situations like this is to recursively gather the failing scenarios in the last run and recheck only them, for a fixed number of recursions.20:03
egaffordvgridnev_: It's risky, because it allows random test or prod code error to go unseen sometimes, but if we're manually hitting sahara-ci-recheck several times until the whole set of tests works at once anyway, we're not doing ourselves any real favors.20:04
egaffordelmiko: I'll bring up the possibility at the next weekly. Playing the CI slot machine game wastes enough cluster and dev time that it's worth at least talking about the option.20:08
*** zhiyan has quit IRC20:08
elmikoegafford: agreed, my impression is that fixing the weird issues (like clusters coming up in error state) is a deep well20:09
egaffordelmiko: Sure; any system with this much complexity and asynchronicity is going to be very hard to write reliable CI for, always.20:10
vgridnev_In general, I think current recheck-strategy have same risk of passing "random" code20:11
*** hdd has joined #openstack-sahara20:11
elmikoegafford: imo, much of it comes from the non-deterministic nature of spawning this many clusters for testing. there are bound to be hiccups. doesn't mean we shouldn't strive to make it better though.20:11
egaffordvgridnev_: Exactly.20:11
egaffordelmiko: I agree; we should strive to make it better. I'm just suggesting that we automate around the current pain points. (This message brought to you by the one-line manifest commit in stable/juno, which after passing CI several times, failed CI twice after the stable/Juno Jenkins issue was resolved.)20:13
egaffordelmiko: (On different tests each time.)20:14
*** zhiyan has joined #openstack-sahara20:18
elmikoegafford: +1, i don't have any issue with adding some level of auto-recheck20:20
elmikoi thought some of that was in there already, but i don't know all the internals of the testing infra20:21
elmikoegafford: has you looked into zuul and gate process?20:21
egaffordelmiko: I haven't; I assumed that we were not auto-rechecking, given the number of random failures I'm seeing. I guess I should rephrase: if we are auto-rechecking, I am concerned.20:24
elmikoegafford: yea, i'm not sure20:24
egaffordelmiko: (In a different direction.)20:24
elmikozuul is kinda cool though, it does this massive testing dance with all the patches that are being submitted across all tagged projects. then attempts to pipeline various combinations of commits, really cool stuff imo.20:25
elmiko(also causes some headaches, but....)20:25
