1. As with most other distributed systems, the Apache Mesos, in order to simplify the design, also employs a master/slave structure that, in order to solve the master single point of failure, makes master as lightweight as possible, and the above number It can be reconstructed through various slave, so it is easy to solve the single point of failure by zookeeper. (What is Apache Mesos?) Reference: "Unified resource management and scheduling platform (System) Introduction", this article analysis based on MES ...

1. The foreword Scheduler is the core component of Mesos, which is mainly responsible for allocating resources on each slave to each framework, and the common scheduling mechanism is Fifo,fair scheduler,capacity Scheduler,quincy,condor. Mesos in order to support the multi-framework access, the two-layer scheduling mechanism is adopted, first, the resource is allocated to the framework by the allocator in Mesos, then the framework itself ...

1. The introduction of Mesos is mainly composed of four components, respectively, Mesos-master,mesos-save,scheduler and executor, each component is based on protocal buffer actor Model for communication (using Open Source Library libprocess). In other words, each module is a server (in fact, the socket server), listening to messages from other modules, once received a message ...
