--------------------------------------------------------------
We've proceeded further with the review and here's the updated list of changes:
https://reviews.apache.org/r/44287/ : Added MasterContender and MasterDetector
abstract classes.
https://reviews.apache.org/r/44288/ : Changed MasterDetector/Contender
namespace.
https://reviews.apache.org/r/44543/ : Removed unnecessary MasterContender and
MasterDetector definitions.
https://reviews.apache.org/r/44544/ : Moved contender and detector definitions
into separate directories.
https://reviews.apache.org/r/44545/ : Instead of keeping standalone and
zookeper contender/detector class
definitions and implementations in the same file, separated them. Also
made the necessary changes in users of class headers to point to the
new locations.
https://reviews.apache.org/r/44546/ : Moved functions in promises to a common
header file.
https://reviews.apache.org/r/44547/ : Added functions in promises to the
collect header.
https://reviews.apache.org/r/44289/ : Added support for contender and detector
modules.
https://reviews.apache.org/r/44669/ : Added createFromModule methods to
MasterContender and MasterDetector.
https://reviews.apache.org/r/44670/ : Added master_detector and
master_contender flags.

> URL: https://issues.apache.org/jira/browse/MESOS-4610
> Project: Mesos
> Issue Type: Improvement
> Components: master
> Reporter: Mark Cavage
> Assignee: Mark Cavage

>
> Currently mesos depends on Zookeeper for leader election and notification to
> slaves, although there is a C++ hierarchy in the code to support alternatives
> (e.g., unit tests use an in-memory implementation). From an operational
> perspective, many organizations/users do not want to take a dependency on
> Zookeeper, and use an alternative solution to implementing leader election.
> Our organization in particular, very much wants this, and as a reference
> there have been several requests from the community (see referenced tickets)
> to replace with etcd/consul/etc.
> This ticket will serve as the work effort to modularize the
> MasterContender/MasterDetector APIs such that integrators can build a
> pluggable solution of their choice; this ticket will not fold in any
> implementations such as etcd et al., but simply move this hierarchy to be
> fully pluggable.
