Re: Does Mesos support Hadoop MR V2

Porting YARN to run atop Mesos is quite reasonable. Some folks at eBay have started some work on this (https://github.com/mesos/myriad). If you're interested, you should check it out, and contribute to the project. On Tue, Oct 28, 2014 at 5:21 AM, Yaneeve Shekel yaneeve.she...@sizmek.com wrote:

Thanks for the explanation John, that's very useful. I wasn't aware each job in MRv2 was considered it's own entity to the scheduler, that's interesting... I think Maxime's point about some kind of hadoop compatible framework would work well, it sounds to me like the FrameworkExecutorTask flow

When I said that running yarn over mesos did not make sense I meant that running a resource manager in a resource manager was very sub-optimal. You will eventually do static allocation of resources for the Yarn framework in Mesos or have complex logic to determine how much resource should be given

So excuse my naivety in this space, but my ignorance has never really stopped me from asking questions: I see YARN (Yet another resource negotiator) as very similar to Mesos. I.e. something to manage resources on a cluster of machines. So when I hear talk of running YARN on Mesos it's seems very

I second john's opinion on the confusing part of different terminology of hadoop v2. That's the reason I asked the question on if mesos support mr v2. As maxime's concern, the decoupling part might be difficult. After reading the mesos mrv1's implementation, I think possibly mrv2 migration can

I haven't written yarn app masters myself and browsing the hadoop-mapreduce-project directories is really not easy. I think it is feasible to get a prototype to work but it would take time. From what I know one difference is that the app master (which is equivalent to the mesos framework) is run

I am interested in investigating the idea of YARN on top of Mesos. One of the benefits I can think of is that we can get rid of the static resource allocation between YARN and Mesos clusters. In that way, Mesos can allocate those resources that are not used by YARN to other Mesos frameworks like

Hey Luyi, That's correct, the Hadoop framework currently only supports Hadoop 2 MRv1. It also doesn't have great support for the HA jobtracker available in newer versions of Hadoop, but I've been working on that the past few weeks. I'm not sure how Hadoop 2 would play with Mesos, but very

I've not seen any issues pertaining to running many short lived frameworks, but that's not near the number of frameworks you'd see if each job was a framework. We've been pushing all our work on MRv1 High Availability JT upstream on the github.com/mesos/hadoop repo, though there hasn't been much
