scouzigouHello! I started playing with Horton Data Flow (HDF) (http://hortonworks.com/products/data-center/hdf/). Do you know if the integration of HDF is planned (already done?) ?09:40

exploreshaifaliHello!11:13
exploreshaifalido I need to necessarily have devstack installed to contribute to Sahara?11:14
*** GB21 has joined #openstack-sahara11:15
vgridnevexploreshaifali, in most cases, yes, you will need an environment to validate your changes are good enough to be merged.11:16
exploreshaifalivgridnev, I was reading this - http://docs.openstack.org/developer/sahara/devref/development.environment.html#setup-a-local-environment-with-an-external-openstack11:17
exploreshaifalibut not sure what exactly "with an external openstack" means11:18
exploreshaifaliI thought it is something without any devstack installation, is that the case? vgridnev11:18
vgridnevNope11:18
exploreshaifalivgridnev, okay, will you mind explaining what does it mean?11:20
vgridnevI means, that you have an installed OpenStack somewhere (some kind of lab, or something like that). For example, I'm using a lab with deployed OpenStack Mitaka for development. Sahara itself is installed in virtual machine, and it have access to this lab.11:21
vgridnevlab with OpenStack mitaka is common, and several engineers are using that for tests.11:23
exploreshaifalivgridnev, yea, make sense. Thanks! :)11:23
exploreshaifaliyup. gottcha! Thanks!11:23
vgridnevscouzigou, around? is it different from HDP, right? It seems like it also can be deployed using ambari, and it seems like a thing which can be done in terms of Sahara.11:26
*** GB21 has quit IRC11:33
*** dave-mccowan has joined #openstack-sahara11:35
exploreshaifaliI am trying to understand Sahara codebase, is there any webpage that I could help me for same? I am looking at shara github repo and got shara architecture http://docs.openstack.org/developer/sahara/architecture.html here11:43

*** nkrinner has joined #openstack-sahara12:07
scouzigouvgridnev: HDF can be deployed using ambari. The only difference is that it is necesserary to install "HDF management pack" first (see chapter 2.3 : http://docs.hortonworks.com/HDPDocuments/HDF2/HDF-2.0.0/bk_ambari-installation/content/index.html). Then, installing the services, etc. should be possible using Ambari blueprint...12:39

exploreshaifaliwhat sahara conductor is about? Is it similar to nova-conductor, which help other nova components to talk to nova database?13:23
vgridnevexploreshaifali, yep, almost same purpose13:37
exploreshaifalivgridnev, but we also have a db directory there in sahara code base, so this db is the one which actually talk to database and manage all operations of db related to Sahara...and the conductor is interface for other sahara components to talk to database?13:40

*** GB21 has joined #openstack-sahara14:01
exploreshaifalivgridnev, the service package in sahara seems to do a lot of stuff, as it name says, I think it serve all services to sahara users... that is orchestration, edp, monitoring14:26
exploreshaifalithere is one package for each service, like for orchestration there is heat package, for edp there is epd package, for monitoring I think there is health package14:27
exploreshaifalibut what validations and castellan packages are for?14:28
exploreshaifaliegafford, \o14:32
egaffordexploreshaifali: o/14:32
exploreshaifalicurrently, I am trying to understand the code-structure of sahara14:33
*** carlos__ has joined #openstack-sahara14:33
egaffordexploreshaifali: validations is about generally validating inputs from clients to make sure they're actually going to be useful to send to the engine.14:33
egaffordcastellan is an OpenStack library that serves as an abstraction for key management (secure secret storage). It usually wraps Barbican, which is the OpenStack secure secret store.14:34
exploreshaifaliegafford, okay. Thanks!14:35
egaffordexploreshaifali: NP!14:35
carlos__Hello all. Is this the correct place if I want support for Sahara?14:35
exploreshaifaliegafford, My laptop's hinge is kinda broken...I am gonna give it for repair....whole process will take around 2 to 3 days...will just read and understand sahara stuff by that time14:36
egaffordexploreshaifali: Always a good idea.14:37
exploreshaifali:)14:37
vgridnevcarlos__, I think so14:37
egaffordcarlos__: This is certainly a correct place to ask questions about Sahara.14:37
egaffordIt's the Sahara dev team room; we're happy to help if we can.14:38
carlos__:)14:45
carlos__Well, I'm trying to install sahara. I'm installed following the guide here: http://docs.openstack.org/developer/sahara/userdoc/installation.guide.html14:46
carlos__My OpenStack release is mitaka and I've used mitaka tarball: http://tarballs.openstack.org/sahara/sahara-stable-mitaka.tar.gz14:46
toskyand the rest of OpenStack? I mean, maybe your OpenStack distribution provides packages for Sahara14:47
carlos__All openstack packages installed on my system are from Mitaka Release (Ubuntu)14:52
carlos__problem is if I try to run for example "sahara cluster-list" it fails and a cryptic message appears: Internal Server error14:53
carlos__And I haven't had a single clue about what is happening, nothing appears on the logs...14:53
vgridnevwhat's happening at sahara logs?14:54
carlos__2016-11-02 14:57:34.524 59698 DEBUG keystonemiddleware.auth_token [-] Authenticating user token process_request /opt/sahara-venv_master/local/lib/python2.7/site-packages/keystonemiddleware/auth_token/__init__.py:34614:58
vgridnevcarlos__, could you please post that logs to paste.openstack.org ?14:59
carlos__sure, would you like to take a look to my config file too?14:59

carlos__with users / passwords removed of course :)15:07
*** esikachev has quit IRC15:08
vgridnevwhat about logs?15:09
carlos__just a minute15:09
carlos__logs => http://paste.openstack.org/show/587652/15:14
*** tosky has joined #openstack-sahara15:20
vgridnevcarlos__, sorry, I have to go, but from logs seems like you most probably have some kind of issues with messaging15:21
vgridnevegafford, are you still around?15:21
*** exploreshaifali has quit IRC15:22
carlos__@vgridnev don't worry i'll try to solve it in the meantime15:22
*** zemuvier has quit IRC15:24
egaffordvgridnev: Yup; I can try to help a bit.15:25
egaffordReading logs now.15:26
egaffordAgreed with vgridnev's assessment that messaging is the most likely issue. Checking configs.15:27
egaffordcarlos__: Are sahara-api and sahara-engine both logging to this file?15:27
egafford(And if not, which are we seeing?)15:28
carlos__Yes, can I split them on separate files? I don't see any config option to do that15:28
*** vgridnev has quit IRC15:28
carlos__Messaging have been working fine for the rest of my OpenStack Infrastructure (Neutron, Glance, Cinder, Nova...)15:28
*** esikache1 has quit IRC15:29
*** esikache1 has joined #openstack-sahara15:29
egaffordcarlos__: These seem suspicious:15:30
egaffordauth_uri = https://public_endpoint:5000 auth_url = https://admin_endpoint:3535715:30
egaffordAre these valid URLs in your env?15:30
carlos__no, of course15:30
carlos__do you need them?15:30
egaffordNo, not at all.15:31
egaffordJust wanted to make sure that wasn't the literal text of your conf via some manner of missed placeholder.15:31
egaffordSeemed like a stretch but one never knows.15:31
*** esikache1 has quit IRC15:34
egaffordcarlos__: If you're running both sahara-api and sahara-engine in --debug, I'm reasonably comfortable saying that no messages are reaching your engine. Are these the same keystone_authtoken and oslo_messaging_rabbit values you're using in other service then?15:36
