flaviodsrhi guys, just installed sahara stable/mitaka and everything looks good, however when I try to run the pig job from sahara-tests, the job is getting killed. Trying to debug it, job-show is showing "errorMessage": "Method POST on http://10.5.0.31:5000/v3/auth/tokens/ failed, status code: 504, status line: HTTP/1.0 504 Gateway Time-out" and keystone logs are14:20
flaviodsrshowing http://paste.openstack.org/show/498252/ every time I try to tun the job. Does anyone have any idea whats happening?14:20

openstackgerritMerged openstack/sahara-ci-config: Remove ambari 2.4 from zuul mitaka  https://review.openstack.org/31797114:23
toskydoes it happen also for other jobs?14:27
*** logan- has quit IRC14:29
flaviodsrit does, tried with a mapred job with same result14:29
flaviodsrjust checked there is a bug report similar to whats happening to me (https://bugs.launchpad.net/sahara/+bug/1504140), I will try the workaround14:30
openstackLaunchpad bug 1504140 in Sahara "[Swift] Wrong HADOOP_SWIFT_AUTH_URL for hadoop config" [Undecided,New] - Assigned to Esteban Arias (eariasn)14:30
*** logan- has joined #openstack-sahara14:30
toskyuhm, I didn't see it in my configuration; if I understand the bug correctly, it depends on how the endpoint was configured (with or without the slash)14:33

flaviodsrtosky looking into the code I see https://github.com/openstack/sahara/blob/master/sahara/swift/utils.py#L34, however am I right assuming that using sahara_proxy should work against keystone api v3?16:07
toskyuhm, good question, I don't remember how/if it changed16:12
toskyelmiko: do you remember something about that? ^^16:12
* elmiko looks16:12
openstackgerritAnant Patil proposed openstack/sahara: DNM: Testing with heat convergence engine  https://review.openstack.org/31666716:13
elmikoflaviodsr: if you are using the proxy domain user feature, then yes keystone v3 is needed16:13
elmikoit will *only* work against v316:13
elmikoin these cases, the hadoop node images need to have our version of the hadoop-openstack.jar. (this is handled by our image gen. process)16:14
elmikothere is an upstream (from apache) version of hadoop-openstack.jar, but it only handles v216:14
flaviodsrelmiko ok good! I am using keystone v3 and this image http://sahara-files.mirantis.com/images/upstream/mitaka/sahara-mitaka-vanilla-hadoop-2.7.1-ubuntu.qcow216:15
*** nkrinner is now known as nkrinner_afk16:16
flaviodsrhowever my job is getting killed and on keystone logs I see http://paste.openstack.org/show/498252/ whenever I run a job16:16
elmikoweird16:18
elmikoare you using the proxy domains?16:19
flaviodsryes16:19
elmikohmm, you could always remake the hadoop-openstack jar from our sahara-extras repository to double check that the proper jar is in place16:20
elmikoi am unfamiliar with those errors coming from keystone. i haven't seen that before16:20
flaviodsrI tried without proxy domain, and got http://paste.openstack.org/show/498692/16:21
elmikowhen you switch to no proxy domain, did you add the user credentials to the swift objects?16:22
flaviodsrI did16:22
elmikohmm, really odd16:22
flaviodsrI updated the data sources, both input and output, with my keystone credentials16:23
elmikoit certainly sounds like the hadoop nodes aren't sending the proper creds for the keystone interaction16:23
elmikohmm, are you using TLS internally for all endpoints?16:23
flaviodsrno16:24
elmikohuh16:24
*** dmk0202 has quit IRC16:24
*** ig0r_ has quit IRC16:24
flaviodsrI also checked for the proxy_user_role_names if they have access to swift, and they do16:25
elmikoi wonder if we've introduced a regression with regards to newer keystones, that version looks pretty new16:25
*** esikachev has quit IRC16:26
elmikoand does your proxy domain support user creation?16:26
flaviodsryes, its a sql backend16:26
elmiko(ie is it backed by database and not kerb)16:26
elmikok16:26
elmikosounds like you've done your homework well ;)16:26
flaviodsr:)16:26
flaviodsrI have seen the users being created on sahara_proxy domain when I rung the job, and being deleted when the job gets killed16:27
elmikousually, when i run into issue like this, i do a couple things. look at the hadoop logs on the nodes to see if they report any additional errors, and then i have rebuilt the hadoop-openstack.jar from sahara-extras and manually deployed16:27
elmikook, so that part is working. it's just the nodes aren't communicating16:28
*** catintheroof has quit IRC16:28
elmikoi have a meeting, i'll be back around in a little bit16:28
flaviodsralright, I will try the hadoop-openstack.jar build and I can get back later16:28
elmikogood luck!16:29
flaviodsrthanks elmiko and tosky!16:29
flaviodsr:)16:29
toskyor you can even try a full build of the guest image using sahara-image-elements16:29
flaviodsrsure! gona take a look into it!16:30
