Hi Kant,
 
What exactly are you planning to work on? Modularising interfaces or Consul module? Either way, we would welcome you to the community. You could go through the contributor guide here http://mesos.apache.org/community/ and file a PR on github to be added as contributor, see example here: https://github.com/apache/mesos/pull/167 . Also you need to ask some guy to add you to JIRA, then you'll be able to assign tasks.
 
cheers,
/J

Kant,
 
we would love to walk new community members through the code! We understand how important it is to have a more experienced member of the community to help out with patches, hence we have "shepherds". Moreover, though technically possible, is not advised to start working without having agreement with your shepherd.
 
Joseph Wu is driving the effort, get in touch with him and I'm sure you'll figure out the plan!

@Alex Rukletsov I am sorry I took some time to respond. I am very excited since the beginning to have an opportunity to work on this task but I wanted to take my time if I can really commit to the Task and looks I might be able to however I have not contributed to open source before and I would need some help from someone who can point me to the right parts of the code and basically help me navigate through the process and if that is feasible I will be happy to commit some time every week to work on this. please let me know if that works.

Frameworks would use the redirect mechanism of the HTTP API and in case of unteachable nodes could do round robin on the list of master nodes.

And for discovery of other nodes in the Paxos group.

The work on modularizing/decoupling Zookeeper is a prerequisite for having the replicated log perform leader election itself.  <- That would merely be another implementation of the interface we will introduce in the process:

Also, I think, the replicated log itself uses Zookeeper for leader election.

If we use the replicated log for leader election, how will frameworks detect the leading master? Right now the scheduler driver uses the MasterInfo in ZK to discover the leader and detect leadership changes.

If we go and change this, why not simply remove any dependencies to external systems and simply use the replicated log for leader election?

Kant—
 
thanks a lot for the feedback! Are you interested in helping out with Consul module once Jay and Joseph are done with modularizing patches?

Patches are currently under review by @Joseph and can be found at the links provided by @haosdent.
 
I took a quick look at Consul key/value HTTP APIs and they look very similar to Etcd APIs. You could actually reuse our Etcd module implementation once we manage to push the module into Mesos community.
 
The only technical problem I could see for now is that Consul does not support `POST` with incremental key index. We may need to leverage `?cas=<index>` operation in Consul to emulate the behaviour of joining a key group.
 
We could have a discussion on how to implement Consul HA module.

Jay has some patches for de-couple Mesos with Zookeeper
 
 
I think it should be possible to support consul by custom modules after jay's work done.

Hi Alex,
 
We have some experienced devops people here and they all had one thing in common which is Zookeeper is a pain to maintain. In fact we refused to bring in new tech stacks that require Zookeeper such as Kafka for example. so we desperately in search for alternative preferably using consul. I just hear lot of positive response when comes it consul. It will be great to see mesos and consul working together in which we would be ready to jump at it and make a switch for YARN to Mesos.
 
Thanks,
Kant

mind telling us what is your use case and why this ticket is important for you? It will help us prioritize work.

Hi guys, i always focus on t his case. but good news is etcd always have patchs. so the coming consul is very easy, just need some time to do coding on it. if you have interesting it? let us collaborate it.

There is no timeline as no one has done any work on the issue.

Hi Guys,
 
I see this ticket and other related tickets should be part of sprints in 2015 and it is still not resolved yet. can we have a timeline on this? This would be really helpful
 
 
Thanks!
