 Hi, I'm welcome to the student series Ptl interviews. I'm here with Vitaly Gridnev with the Sahara project. Vitaly, can you introduce yourself and give us a little bit about your OpenStack background? Okay, thank you. I'm Vitaly Gridnev and I'm working with Mirantis, software engineer working at Saratov Office. So, I'm project technical lead of OpenStack data processing called name Sahara. And I'm working with Mirantis since killer release and with OpenStack also since killer release on June 9. Oh, great. Can you tell us a little bit about the Sahara project and what it does? Sahara project, the general aim of the Sahara project is to provide simple way to deploy open, deploy Hadoop clusters on top of the OpenStack. So, right now we can create several templates and create Hadoop clusters in a single click. And then you can perform a elastic data processing application on top of these clusters. So, that is a general aim of the Sahara. Great, cool. So, at the Austin Design Summit what were some of the hot topics with the Sahara team and what were some of the decisions and outcomes from those discussions? There are several hot topics on the Austin Summit. First of all, we discussed several API improvements that we really need to do in this ISO and also to implement new version of API called API v2. So, our plan to implement several changes to that and make that stable so that other folks can try that and also try to support that in Sahara client also. Okay, another hot topic was the image generation improvement that right now we have several and work required before launching the cluster so that users need to generate images and something like that. So, we are going to write several re-scipes for validation images and also try to create a simple way to generate images for current OpenStack deployment. And also there are several topics regarding the GDP improvements, elastic data processing, I mean, and also about security in the Sahara clusters. Great, were any of those discussions or topics the result of identifying operator or user needs? And can you kind of discuss how you found out about those needs and then how that drove decision making within the Sahara team? So, the general outcome for users that sometimes it's really too hard to understand from Sahara what is going on and so we are trying to make the changes to improve that and also sometimes there are some problems with managing and preparing Hadoop clusters so that is also a thing that we are going to do. Great, awesome. And what are the top three priorities for kind of new features or enhancements that the Sahara team are working on? So, the general top three, I think that first of all, the image generation improvement, I guess, as I said previously and also regarding the security for the clusters, several GDP improvements, elastic data processing and finally API as I said. Great. Do you think about those improvements in terms of any of the kind of common themes we hear across OpenStack like scalability, resiliency, manageability, modularity or interoperability and can you kind of describe how those improvements fit into the themes? So, I think that for us the manageability theme will touch us in this size select. I think that many changes we always do to improvement, to UI improvements and something like that and we, almost everything is okay with scalability for Sahara right now. By the way, maybe we will do some things in Newton or not Newton, I mean Akata and probably some kinds of resiliency also will be done in Akata maybe, I guess. Great. So, you mentioned the themes for resiliency and scalability in Akata. Any kind of foreshadowing of what those topics might be, what we might look to expect from the Sahara project in the Akata cycle? So, I guess that in Akata will be some kind of a cherry for deploying the cluster. So, right now if Sahara will probably die during the provisioning cluster there is no way to restore that cluster and we are going to make some several changes I guess in Akata to improve that. Awesome. Well, this was very helpful and informative. I appreciate your time today and especially your leadership on the Sahara project. Okay. Great.
