frippe75Any pointers on setting up node-group-templates for the using the hortonworks distro?11:02
frippe75ambari plugin..11:02
toskyfrippe75: do you mean something like https://docs.openstack.org/developer/sahara/userdoc/ambari_plugin.html#cluster-validation ?11:05
frippe75tosky, no, actually looked at that. More of how to define the different nodegroups and the bare-minimum node processes in a 1+2 cluster needed.11:07
toskyyou can check what we use for the scenario tests: http://git.openstack.org/cgit/openstack/sahara-tests/tree/sahara_tests/scenario/defaults/ambari-2.4.yaml.mako11:09
frippe75my lacking hadoop skills makes me not understand the mix of node processes to get up and running. Seen example where you select "ambari server" and "ambari client" for the different node types. But looking in the list is not that clear how to define a valid worker vs master node.11:09
frippe75Realize the HDP dist could be setup in a more HA config and there requires problably more complex node group templates but I would like to start out with pref. 1 master and then x workers.11:10
frippe75So each time I deploy a cluster in compains about me having the wrong node11:11
frippe75Error: Cluster is missing a service: HBase Master, required by service: HBase RegionServer11:11
frippe75So here quite obvious. "HBase Master" in my HDP-master node group template, and "HBase RegionServer" in the HDP-worker node group template. But for others not so obvious.11:12
frippe75So a quickstart doc. to get a simple cluster fired up.11:13
toskyas I said: check the examples above11:13
toskythose works11:13

frippe75tosky, I was so busy typing I missed that comment. Sorry! looking now and ... looks like what I needed. Thanks!11:14
toskyfrippe75: you can probably use something even smaller (you can probaby have a unique master instead of master and master-edp, iirc), of course with bigger instances11:15
frippe75tosky, will start out with the full scenario one to get something tested up and running and minimize from there. thanks again!11:17

frippe75tosky, took that example removed all mako placeholders. Changed flavors/images and so on to my settings. Did a openstack dataprocessing cluster template create --json <file>12:36
frippe75create() got an unexpected keyword argument 'plugin_version'12:36
frippe75Looking at the quickstart. https://docs.openstack.org/developer/sahara/devref/quickstart.html12:36
frippe75there is no plugin_version only hadoop_version... Which does not sound very futureproof having other than hadoop for dataprocessing. So I guess the quickstart might be incorrect. Cannot get around this.12:37
toskydid you try hadoop_version instead?12:37
* tosky rechecks12:38
frippe75:-) no.. .not yet.12:38
frippe75Thought the Sahara nightly tests would have picked that up along time ago. But since there is not yaml import using the openstack client "you" might be doing something differently.12:39
toskythe yaml files in http://git.openstack.org/cgit/openstack/sahara-tests/tree/sahara_tests/scenario/defaults/ambari-2.4.yaml.mako12:39
toskyare not in the format used by `openstack dataprocessing ...` client12:39
toskythey are in their own custom format used by the scenario test runner12:40
toskyso you can be inspired by them but follow the quickstart guide, which uses hadoop_version12:40
frippe75starting to understand that since I now get a new invalid argument.12:40
toskyprobably if I recall correctly for historical reasons (and we are not going to change until API v2, under (slow) construction)12:41
toskybut anyway, please follow the structure of the quickstart guide12:41
frippe75I will! thanks for be so responsive!12:41
toskymost of the people are going to the PTG this week12:42
frippe75I see. Atlanta...12:42

frippe75tosky, Sorry for bothering you. Looked at the provided templates for a hdp cluster.15:48
frippe75Error: Hadoop cluster should contain 1 YARN Timeline Server component(s).15:48
frippe75Understand I should put it master or secondary master but still. Alot of work getting it up and running.15:49
toskyyes, and it was defined in master15:49
toskyhttp://git.openstack.org/cgit/openstack/sahara-tests/tree/sahara_tests/scenario/defaults/ambari-2.4.yaml.mako#n1715:50
frippe75maybe I''m confusing the ambari plugin with hdp?15:50
toskythe ambari plugin deploys hdp >=2.415:50
toskythe old hdp plugin deployed up to 2.0.615:51
toskydeprecated and removed for a while15:51

frippe75tusky, had some issue with available resource but deleted ALL stacks on my 32GB system (all-in-one-node). So after the resource issue was solved, "RemoteCommandException: Error during command execution: "rngd -r /dev/urandom -W 4096"". using sahara-ambari-latest-ubuntu21:38
frippe75Downloading http://sahara-files.mirantis.com/images/upstream/newton/sahara-newton-ambari-2.2.1.0-ubuntu.qcow221:42
frippe75to see if that solves that issue...21:42
frippe75just realized.. this is the one I'm using. So wont matter downloading it again :-)21:49
