| ierdem | Hi again, I got stucked while creating HDP 3.0 cluster on sahara. | 11:32 |
|---|---|---|
| ierdem | I will explain you my progress step by step. Please tell me where I went wrong. | 11:32 |
| ierdem | First, I moved my sahara venv to infra host, because guestfs needs to kernel and lxc containers uses host kernel so guestfs does not work on containers | 11:32 |
| ierdem | Secondly, I add necessary packages for guestfs and downloaded proper image (tosky helped me, thanks again) | 11:32 |
| ierdem | Thirdly, I changed ambari/plugin.py, ambari/deploy.py, ambari/resources/images/image.yaml files on venv(added necessary codes for HDP 3.0 and ambari 2.7.1) | 11:32 |
| ierdem | After this, I crated ambari 2.7.1 image and uploaded this to glance. Also I changed sahara container venv with the same way | 11:32 |
| ierdem | Lastly, I restarted sahara services and I could see HDP 3.0 plugin as a choosible version on Sahara, I created templates and started the cluster | 11:32 |
| ierdem | At this point, Sahara works fine till it comes to "Configuring" step. When it comes to "Create Ambari Blueprint" step, throws an error, "Error during operating on cluster (reason: 400 Client Error: Bad Request for url: http://10.1.117.39:8080/api/v1/blueprints/pack2-test)" | 11:32 |
| ierdem | We are using HDP 3.0 with Sahara on OSA Pike and OSA Stein versions, but can not on Ussuri. What am I missing? Can you help me about this, please? | 11:32 |
| ierdem | By the way, I add configs-3.0.json to resources in third step | 11:33 |

| tosky | ierdem: as I mentioned yesterday, I remember that Sahara tries to configure ambari username and password; maybe that step doesn't work anymore, or it needs to happen earlier than before | 13:04 |
| ierdem | tosky, I checked it, "Update default Ambari password" step is before "create ambari blueprint" step but you may be right. How can I correct this in this situation. I may be miss something but when I compare the stable/stein and stable/ussuri branches there is no changes on sahara_plugin_ambari | 13:08 |
| tosky | it's ambari that changed | 13:11 |
| tosky | everything has been tested up to ambari 2.6, so maybe ambari 2.7 is a bit a different | 13:13 |

| ierdem | We solved the problem, it was about validation process of the blueprint. I forgot to change service names in common.py. So When I try to deploy cluster which consist HiveServer, it gave error because in HDP 3.0, HiveServer's name is HiveServer2. We correct the syntax and it seems works fine for now. Thank you for your helps. I will test all the | 14:31 |
| ierdem | services. After that I want to arrange the code with you, and at the end I want to contribute | 14:31 |
| tosky | oooh | 14:32 |
| tosky | something had to be different :) | 14:32 |
| tosky | nice to hear the issue was solved | 14:33 |
| tosky | only one thing: I'm not sure about how to move forward, but if the older HDP is still supported, the change to the code should try to keep the compatibility with the old code | 14:33 |
| tosky | but let's discuss it, sure | 14:33 |
| jeremyfreudberg | ierdem: good news! | 14:37 |
| ierdem | Actually, I knew I was forgot something little, I practice this upgrade process at least 5 times but sth like this may happen when you try to be fast:) | 14:37 |
| ierdem | jeremyfreudberg, tosky I will test the services and I will prepare the documentation. By the way I want to share code with you next week but I did not contribute anything before, so I may need help about it :) | 14:39 |
