_crobertsrhHey folks, if you're looking for a good UI review to take a look at, please give https://review.openstack.org/#/c/209683/ a go.  Lots of good functionality to try out, even if you're not into boring UI code :)14:43
egaffordThanks _crobertsrh!14:44

openstackgerritVitaly Gridnev proposed openstack/sahara: Create ResourceGroup with volumes only it is required  https://review.openstack.org/22053814:48
vgridnevegafford, is there simple way to try that?14:50
openstackgerritAshish Billore proposed openstack/sahara: Update Sahara Dev Quickstart Guide  https://review.openstack.org/22024514:50
vgridnevegafford, I'm talking about your horizon patch14:51
egaffordvgridnev: Well, you can fetch that Horizon commit into your devstack at /opt/stack/horizon (or wherever), restart httpd (or whatever) and check it out.14:51
egaffordThat's how I think I'd do it if I weren't doing some weird frankenstein remote development model. :)14:52
egaffordIt's all in the job template creation and launch workflows.14:52
vgridnevOk, will try14:53
egaffordvgridnev: Cool!14:53
ashishb^vgridnev, I have re-submitted the quickstart guide, removing the direct links and putting place-holders for versions14:53
egaffordI was really happy with the way the launch flow turned out in particular; we were able to create a really nice user-specified form for the job.14:53
ashishbhope this is fine now, we won´t have to update it per release / version support14:54
ashishbplease have a look, thanks14:54

rickflarehello all16:48
rickflareI just wanted to introduce myself16:48
tellesnobregahello rickflare, wellcome to sahara16:48
rickflareim a long time systems engineer and I do devops full time16:48
rickflareI have a passion for Hadoop, puppet, saltstack and python16:49
elmikohi rickflare16:49
rickflareI was thrilled when I found out about this project and I look forward to contributing in any way possible.16:49
elmikoawesome!16:49
* egafford has been talking with rickflare: sounds like he's got a lot of really useful experience with the pain of managing large clusters, and enough dev to do something about it. :)16:50
elmikonice, good to hear. we can always use more end-user experience experts =)16:50
*** ashishb has quit IRC16:51
rickflareAs admin of many large hadoop clusters I know how important this will be if done right.16:51
rickflaretools like cloudera manager or horton works are great till you need to do something custom16:52
elmikoright16:52
egaffordrickflare: Yeah... yeah.16:52
rickflareif sahara can scale using apache hadoop then you will win16:52
rickflareI have nothing against cloudera and others16:52
crobertsrhwelcome rickflare......woooooooooooooooo!16:52
rickflareas they work really well16:52
egaffordrickflare: Our mission is to make ALL those guys scale. We've got basic elasticity in all of those. MapR too, I think, though that plugin's newer.16:53
rickflarebut I am fan of running things in a native state and not going too deep down the tunnel, so to speak.16:53
egafford(Also Spark and Storm.) :)16:53
egaffordrickflare: Sure, absolutely.16:53
rickflarewow storm too16:53
rickflarethats impressive16:54
egaffordJust wanted to note that we're distribution-friendly here. :)16:54
egaffordtellesnobrega's been very active in getting Storm up and running.16:54
egaffordTelles, rickflare. rickflare, tellesnobrega.16:54
egaffordOh, tellesnobrega, you already said hi. Good on you.16:55
rickflareone of the biggest issues imo with hadoop is surrounding security. I would love to see projects like freeipa and the use of kerberos implemented with sahara16:55
egaffordrickflare: elmiko's been beating the sec drum pretty hard the last few cycles, so he's your guy there.16:55
rickflarethis way admins can quickly monitor and admin users of the stack and keep details logs of Mapr jobs run by each user16:55
egaffordHe's actually at the security midcycle RIGHT NOW, I think.16:55
rickflarecool16:56
elmikoyes, we are coasting in to the end of midcycle ;)16:56
rickflareso im somewhat new to openstack so I have a learning curve there to deal with.16:56
elmikoand yea, rickflare, i have a presentation about possible integration efforts between sahara and kerberos identity backends16:56
rickflareHowever, I am very serious and want to see this become real.16:56
elmikoi think we have several options to investigate16:56
elmikothere are a number of factors to consider about how we could integrate this piece of openstack with kerberos/ldap16:57
rickflareI think one of the biggest issues is intergration of all these things. As the complexity scales, it reaches a point that when something breaks the system admin has no idea how to fix it.  This is why ease of use and simple structure are key.16:58
elmikoagreed16:58
rickflareelmiko deploying ldap and kerberos from scratch is a major PITA.16:58
rickflareI mean securing ldap alone and making sure your policies are tight can take a long long time.16:59
elmikorickflare: right, although i've been talking with the freeipa guys and they've given me hope that we could do some automation with regards to in-cluster instances of freeipa16:59
rickflaresweet17:00
rickflarewell let me know17:00
rickflareid love to jump in and help17:00
elmikowill do, i'll share my slides with you too if you are curious17:00

egaffordrickflare: If you have trouble with devstack, btw, feel free to ask here. It is a good tool, but not always the stablest, and there is no real need to suffer alone and in silence. :)17:03
rickflareok17:04
rickflarewill do17:04
rickflareim going to get my centos7 box up17:04
rickflarebtw do I still need to remove NetworkManager to get any of this to work?17:05
egaffordrickflare: Fun story: I don't really know on CentOS right now.17:05
egaffordI don't think it'll hurt to disable and remove it, certainly, and you might as well.17:06

tmckayvgridnev, nevermind :)22:06
vgridnevSeems that I solved problem cdh and spark22:06
vgridnevhttps://review.openstack.org/#/c/220500/22:07
tmckaygreat, that's what I was going to work on22:07
tmckaywell, actually, spark/swift22:08
vgridnevyep22:08
tmckayvgridnev, yes, I found out with the default templates that the history server was missing22:08
tmckayI was using a centos image that wouldn't resize, though, and it kept me from launching 5.422:09
tmckayvgridnev, so have you tried spark/swift with this combination?22:09
vgridnevtmckay, I tried on CI and it passed22:10
tmckayok, which test is that in the gate?22:11
tmckayI wanted to verify whether or not the ":" added to the classpath would solve the issue for yarn cluster mode22:12
tmckaybiab22:12
vgridnevprobably ":" addition is unneeded there22:15
