| jkunigk | hello all | 11:57 |
| jkunigk | "Any HDFS instance running on a sahara cluster in the same OpenStack installation is accessible without manual configuration" -> http://sahara.readthedocs.io/en/stable-liberty/userdoc/edp.html | 11:58 |
| jkunigk | Isn't this a multi-tenancy / isolation oops? | 11:58 |
| tellesnobrega | jkunigk, not really. The idea is to give the owner of the cluster access to its data on hdfs if needed | 12:05 |
| tellesnobrega | just like it would happen on a manually deployed cluster, the owner of that cluster (person who has access keys) can ssh to it and see what is happening there | 12:06 |
| tellesnobrega | jkunigk, do you have any concerns on that front? | 12:08 |
| jkunigk | but can tenant A create a cluster in Sahara and tenant B as well and then users from A can access B's HDFS? | 12:09 |
| tellesnobrega | only if they have the private keys | 12:12 |
| tellesnobrega | sahara clusters are not configured with passwords, only user/keypair | 12:12 |
| tellesnobrega | so, anyone with the key can access the cluster | 12:12 |
| tellesnobrega | I don't believe keypairs are shared between two projects, so I would say that Project A users can only access clusters on project A and project B users can only access clusters in project B and only if they can get the private key to the cluster | 12:13 |
| *** alinanesterova has joined #openstack-sahara | 12:15 | |
| tellesnobrega | hey alinanesterova, good to see you around. Do you and esikachev plan to attend PTG? | 12:17 |
| alinanesterova | hey tellesnobrega, no, sadly, we can't visit this ptg at this time | 12:18 |
| tellesnobrega | alinanesterova, that is too bad, hopefully next time | 12:24 |
| tellesnobrega | jkunigk, is there anything else that I can help you with? | 12:24 |
| jkunigk | on a call, but I will reply in a few mins | 12:24 |
| alinanesterova | tellesnobrega: we hope too! by the way, do you have some little tasks for me to contribute to sahara or sahara-tests? | 12:24 |
| tellesnobrega | sure | 12:24 |
| tellesnobrega | alinanesterova, I'm sure tosky can hand you some stuff to do on sahara-tests | 12:25 |
| alinanesterova | okay, thanks! | 12:25 |
| tellesnobrega | tosky, if you have any ideas of tasks to pass on to alinanesterova get in touch with her please :) | 12:27 |
| tosky | uhm, little tasks | 12:27 |
| jkunigk | another question I had was if the plugins (CDH, HWX, etc.) are basically a recipee to install rpms on each of the nodes in the right way / corresponding to the role assignments (e.g. NameNode / DataNode) | 12:29 |
| tellesnobrega | jkunigk, in a simple way they are. They install and configure the nodes to act as the desired role | 12:32 |
| alinanesterova | tosky: maybe i can finish my patch with ispublic isprotected cluster for sahara-tests? is this patch necessary for us? | 12:35 |

| tosky | alinanesterova: yes, it may be useful, even if I completely lost track of the status | 13:02 |
| tosky | there are also few patches still pending (also from other people) which may require some review | 13:03 |
| alinanesterova | tosky: ok got it | 13:05 |
| jkunigk | re packages once again: Sahara does not install e.g. Cloudera Manager or HWX Ambari? | 13:34 |
| *** alinanesterova has quit IRC | 13:36 | |
| *** pgadiya has quit IRC | 13:40 | |
| tosky | Cloudera Manager and Ambari are used in the respective plugins to drive the deployment | 13:41 |

| *** links has joined #openstack-sahara | 15:21 | |
| tellesnobrega | jkunigk, glad you like it | 15:55 |
| jkunigk | is there a form of automatic anti-affinity rules, e.g. for 2 Namenode instances to not run on the same hypervisor, or for datanodes respectively as well? | 15:56 |
| jkunigk | or does that need to be defined manually? | 15:56 |

| *** openstackgerrit has quit IRC | 16:03 | |
| *** tesseract has quit IRC | 16:22 | |
| tellesnobrega | jkunigk, it has to be manually defined. We don't restrict anything on cluster creation related to anti-affinity | 16:39 |
| jkunigk | can I put these in (sorry for laymans terms) "cluster templates"? | 16:39 |
| tellesnobrega | jkunigk, no worries, we are here to help | 16:39 |
| tellesnobrega | let me check | 16:40 |
| *** pcaruana has quit IRC | 16:41 | |
| tellesnobrega | jkunigk, yes, you can select the anti-affinity for processes during cluster template creation | 16:42 |
