elmikoSergeyLukjanov: i'm working on the disconnected hdp plugin patch and i need to adjust how i'm doing things based on the feedback i'm getting. i have a question about using HadoopProvisionError.15:34
elmikoSergeyLukjanov: would it be safe for me to raise that exception in plugins.hdp.hadoopserver if we have no connection to the internet(for downloading hdx rpms) and they are not installed on the instance?15:35

notmynametmckay: any followup needed for the swift tempurl stuff?18:23
tmckaynotmyname, not yet.  We've got some members on PTO currently, we'll have to talk about it.  I'm wondering how secure we want/need to be18:24
tmckayPart of the trouble is that even with a tempurl passed to Hadoop, that url might still be exposed in logs, etc.  I wonder how much of an issue that is18:25
tmckayand predicting the expiration might be tough -- how long will a Hadoop job run?18:26

tmckayhmm, getting a key error on SPARK in  "master_port = cluster.cluster_configs.SPARK.SPARK_MASTER_PORT"18:55
tmckaydoes anyone know in the plugin stuff how cluster_configs is supposed to be extended?18:55
*** IlyaE has quit IRC18:55
*** IlyaE has joined #openstack-sahara18:56
elmikotmckay: sorry, haven't touched that stuff yet18:59
tmckayyeah, I see a dictionary labeled "SPARK" with SPARK_MASTER_PORT in it, but I'm not sure how it's supposed to get to cluster_configs.  The CR says the code is running somewhere.... but I wonder if the CR is broken.19:01
tmckaysome places I can put breakpoints19:01
elmikoyea, next step for me would be print statements or a pdb.set_trace19:02
tmckayI'm wondering if the stuff is in there but the naming is wrong19:03
elmikonot sure how that all plumbs together19:05

tmckayelmiko, looks like maybe an oversight.  cluster_configs are passed as part of the cluster template, apparently.  These values in question should all have sane defaults in Spark.  So, the fact that cluster_configs = {} should be fine.  Missing a conditional, imho.19:40
elmikook, cool. the more you know :)19:40
tmckayI added such conditional and it got past.  But, I got a "permission denied" error during node configuration =-O19:41
elmikohuh19:41
tmckaybaby steps :)19:59

tmckayelmiko, looks like it was trying to create a file as the ubuntu user in a dir owned by hadoop, without world write access20:20
tmckayelmiko, retrying with "run_as_root=True" on the file write wrapper, fingers crossed20:21
tmckayI always wanted to be a sports commentator, this is a close second20:21
tmckaywoohoo!  Spark cluster is active20:23
tmckaywhat, nobody here to celebrate?  Friday before a long weekend or something?  Party in Vegas?  Beverly tasting?20:24
crobertsrh+1 for beverly tasting event.20:24
tmckaywhere's themistymay when you need him20:25
crobertsrhI read that they have it at Epcot...20:25
crobertsrhmaybe that will keep the kids in line when we go there20:25
tmckayYeah, and that's only 12 hours away.20:25
tmckayOr a quick cruise to Atlanta20:25
crobertsrh12?  Maybe for you.20:25
tmckayheh20:25
tmckayGotta love Dixie.20:25
crobertsrhSomething around 20 I think the last time I did it.20:25
tmckayI made that trip a few times from MA20:26
crobertsrhI kind of like the views in KY and TN, but OH and GA are a real bore-fest20:27
tmckayYou sound like a mountain boy20:27
crobertsrhSpeaking of long drives, I wonder how the Mirantis crew is doing :)20:27
tmckayhoping they're in LA by now.  Maybe got held up in Las Vegas :)20:27
crobertsrhsomehow ran out of money in Las Vegas20:28
*** themistymay has joined #openstack-sahara20:28
crobertsrhOk, my reviews are baking in zuul.  Sounds like a fine time to call it a day.  Have a good weekend.20:30
*** crobertsrh is now known as _crobertsrh20:30
elmikotmckay: glad it worked :)20:31
tmckayelmiko, not sure it's the correct solution, but seems to be a workaround20:32
tmckaycommenting on the CR now ...20:32
elmikofrom your description it sounds like there is plenty of debugging to do20:32
elmikodefinitely cool that it works though20:36
tmckayyeah.  whacked that it ends up with 2 files owned by 'ubuntu' in a dir owned by 'hadoop'20:37
elmikoagreed20:37
elmikobut obviously they assumed that it would only be running on ubuntu images or something20:37
tmckayelmiko, yeah, some stuff is being set up as the "hadoop" user though -- either at image build time, or cluster creation.  Not sure.  I guess I can launch just a plain image and find out.20:38
tmckaycould probably just fix this up with a "chown"20:39
elmikothen the ubuntu user is stuff is just an artifact of using ssh?20:39
elmikoyea20:39
tmckayelmiko, yeah, ssh baggage20:39
tmckayelmiko, /opt/spark/conf is in the image, owned by hadoop20:44
elmikois that just a conf file?20:44
tmckayit's a dir20:47
elmikopresumably created by diskimage-create?20:47
tmckayhave to look more, but it looks like what is intended is to modify conf/slaves, and copy and modify conf/spark-env.sh.template to produce conf/spark-env.sh20:48
tmckayelmiko, yeah, rpm install I'm guessing, or something in the spark element20:48
tmckaywell, apt-get :)20:48
tmckayI'm digging holes in someone's backyard20:49
elmikolol totally20:49
_crobertsrhI should have kept working....wife was very happy to see I was done..."Oh good, now you can mow the lawn".20:52
tmckayprobably run as root followed by a chown or some such magic20:52
tmckay_crobertsrh, heh.  I mow tomorrow.  Wife is at a conference.20:52
elmikowait, tmckay aren't some of your kids old enough to mow the lawn?20:59
elmikoi thought that was a main reason to have kids!20:59

tmckayelmiko, yes, technically, some of the kids are old enough21:20
tmckayelmiko, not sure on the qpid/rabbit thing21:20
tmckayI have to teach the kids to drive the riding mower first, though21:21
elmikolol, my dad kicked me out there on the old john deere when i was 1321:24
