openstackgerritChad Roberts proposed a change to openstack/sahara-dashboard: Allowing for HDFS data sources without hdfs://  https://review.openstack.org/9283314:08
elmikocrobertsrh: just looked at that review, what's with the X in workflow?14:16
crobertsrhIt's the new "work in progress"14:16
elmikoahh ok14:17
crobertsrhI'm not really sure that this is the way we want to go long term, but I want to get something available for tmckay to use in his demo14:17
elmikototally, you've got some whitespace in there14:18
crobertsrhI preferred the old "work in progress" method....the one where you'd just click "WORK IN PROGRESS" and it would display "work in progress"14:18
crobertsrhOh, I see...you were just craving a low-hanging -1 review14:21
elmikolol14:22
crobertsrhwhitespace nazi14:22
elmikoi'm trying to help!14:22
elmikobesides, if i didn't get it you know tmckay would have ;)14:23
crobertsrhAbsolutely14:23
openstackgerritChad Roberts proposed a change to openstack/sahara-dashboard: Allowing for HDFS data sources without hdfs://  https://review.openstack.org/9283314:24
elmikowith the work in progress stuff, is it better just to wait until it finished before reviewing?14:26
elmikocrobertsrh: ^^14:34
crobertsrhI'm not offended either way really.  In this case, this is a very early cut just to get something useable for the demo.14:35
crobertsrhFor WIP cases, I tend to leave comments but just go +014:35
*** bradd1 has joined #openstack-sahara14:36
elmikook, thanks. just curious about best practices considering there might be a bunch of churn.14:36
crobertsrhNot sure there is an official "right" thing to do.14:37

elmikoduring the configuration phase of a cluster, is it possible to see what the tasks are?15:17
*** mattf is now known as _mattf15:19
crobertsrhtmckay:  Try the os1 instance now.  I have a tweak up for the hdfs path stuff15:19
crobertsrhlet me know if it meets your needs.  I still need to adjust help text and maybe tweak the UI a bit more15:19
crobertsrhI removed the "prefix" for both swift and hdfs.  For Swift, I check to make sure it starts with "swift://", if not, I add it.  For HDFS, what you give is what you get.15:20
dmitrymeelmiko: which tasks do you want to see?15:22
dmitrymedo you want to see more details than cluster status provides?15:22
elmikodmitryme: well, i'm watching the json output from the /tasks?fields=Tasks and i'm curious what the individual tasks are. for debugging purposes15:23
dmitrymeit is HDP, right?15:23
elmikoyes15:23
dmitrymeeach task has an URL, you can use it15:23
elmikook, i should have seen that lol15:24
dmitrymeif you access it, it will first return Access Denied15:24
dmitrymethen strip all the path part of the URL and go there15:24
dmitrymeyou will see login window15:24
dmitrymelog in with admin/admin (defaults)15:24
dmitrymeand after that you will have access to tasks’ URLs15:25
elmikocool, thanks!15:25
*** zhiyan is now known as zhiyan_15:26
elmikoit looks like putting all the server tasks on one instance is very slooow to setup lol15:27

tmckaySergeyLukjanov, google chrome is telling me that party is over.16:16
aignatovtmckay: try to relogin to you account and open link again16:18
crobertsrhthere's a party going on?16:18
crobertsrhthat's way better than a meeting16:18
tmckayit won't let me view the invitiation either, some conflict between my redhat email and google16:19
tmckayit's because Chrome isn't my default browser, I know it :)16:20
elmikoaww, i got party over too :(16:24
tmckayI'm guessing its because trevormckay2@gmail.com is not in the invitation list16:25

* mattf now with more C21H28O518:33
elmikowhoa!18:33
elmikois that even legal?18:33
mattfapparently18:33
mattfdon't worry, i'm safe. no needle sharing18:34
elmikolol, good to hear18:34
elmikoSergeyLukjanov, aignatov, are there any examples of how to execute_command and wait for the response?18:35
elmikocrobertsrh, ^^ have you ever done that?18:42
crobertsrhI think I'm missing some context18:43
elmikowell, let's say i want to run a command on an instance using execute_command18:44
elmikoand i want to read the result of that command before deciding what to do next18:44
elmikois that a supported pattern, or is it better to put together a bash command to encapsulate the logic?18:44
crobertsrhA script of some sort comes to mind, but there ought to be a way to do what you're trying to do18:48
crobertsrhThat being said, I've never done it18:48
elmikoit looks like i should be able to do it, but when my command runs the execute_command returns immediately with a string about hasn't run yet18:49
crobertsrhIs there another way to call execute_command (any extra params you can send it to make it block)?18:52
elmikoi see a timeout arg, but i don't think that's it18:53
dmitrymeSergeyLukjanov: ooops, sorry, I’ve missed the meeting :-(18:54
elmikoi'm wondering if i need to issue this context.sleep command to wait for the return18:54
dmitrymeelmiko: I know how it works18:54
elmikodmitryme: cool, any advice?18:54
dmitrymeit actually blocks until the command returns. Its result is tuple (ret_code, stdout)18:55
elmikooh, hmm18:56
dmitrymeor its result is (ret_code, stdout, stderr) if you explicitly passed get_stderr=True18:56
elmikomaybe i used it wrong then18:56
dmitrymecan you show your code?18:56
elmikoi was trying to read the ret_code and kept getting "*** Not yet returned!"18:56
dmitrymeso you mean you get a string  "*** Not yet returned!" as the first item in the returned tuple?18:59
dmitrymewhat about the other items in the tuple?18:59
elmikoi only grabbed 1 return value18:59
elmikohttp://paste.openstack.org/show/79638/18:59
elmikoi don't need stdout, just the ret_code19:00
dmitrymethen you should do19:01
dmitrymeretval = r.execute_command(rpm_cmd, run_as_root=True)[0]19:02
dmitrymenote the ending [0]19:02
elmikoayup19:02
dmitrymeregarding the actual value you get, that is really weird19:02
elmikoyea19:02
dmitrymeI can suspect only pdb19:02
elmikoi'll try it again dereferencing the return tuple19:02
dmitrymethough it is really strange even for pdb19:03
