support cross-frame resource sharing, and other scheduling and execution tasks are delegated to the framework to control itself. This sign Mesos not try to be a one-stack problem-solving system, but to realize resource sharing with minimal cost. Let's take a look at the official architecture diagram: Key components and concepts: Zookeeper is primarily used to implement master elections, which support the high availability of master. Master

OverviewApache Mesos is an open source cluster Management suite based on multi-resource (memory, disk, CPU, port, etc.) scheduling that makes fault-tolerant and distributed systems easier.Working principleApache Mesos uses the master/slave structure to simplify the design, making master as lightweight as possible, preserving only the state information of the various computing frameworks (framework) and

processes terabytes of data in parallel on a large cluster. Previously, each new distributed system, such as Hadoop and Cassandra, needed to build its own underlying architecture, including message processing, storage, networking, fault tolerance, and scalability. Fortunately, systems like Apache Mesos simplify the task of building and managing distributed systems by providing similar operating system-like management services to key building blocks o

above. This open source software The project is both a Mesos framework and a YARN scheduler, enables Mesos to manage YARN res Ource requests. When a job comes into YARN, it'll schedule it via the Myriad Scheduler, which'll match the request to incoming Mesos R Esource off

use zookeeper to solve the master single point of failure.Mesos Master acts as the global resource scheduler, using a strategy algorithm to assign idle resources on a slave to a framework, while various frameworks are registered with the master through their own schedulers for access. Mesos Slave is a executor that collects task status and launches various frameworks. The working schematic is as follows.Ap

The total number of recommended nodes is 5, in fact, the production environment requires at least 3 master nodes. Mesos decided to design Master to hold the software state, which means that when the master node fails, its state can quickly be rebuilt on the newly e

. Mesos-slave sends its own amount of resources to mesos-master, which is determined by the allocator module in Mesos-master to which framework the resource is allocated, and the resources currently under consideration are both CPU and memory, that is, Mesos-slave will send the number of CPUs and the amount of memory t

Protocal Buffer message processors are registered in each service. Once a message is received, the corresponding message processor is called for processing. In addition to the above four services, Mesos also provides three programmable components: Alloctor, Framework schedtor, and Framework Executor.
