DCOs as the bottom support platform for running Docker, our workload is reduced a lot, but because of the large number of Docker, even with the overlay network, but IP address AH port number AH so much, we can be good. Right, this time marathon-lb appeared, the approximate process is as follows:1. We run Docker, hit a random port A, and tell ZK which Port B we want to have to be accessed by someone else.2. MARATHON-LB will go to ZK to find this port B

Create a distributed system using line 1 code using Mesos, Docker, and GoIt is very difficult to build a distributed system. It requires scalability, fault tolerance, high availability, consistency, scalability and efficiency. To achieve these goals, a distributed system requires many complex components to work collaboratively in a complex way. For example, when Apache Hadoop processes terabytes of data in parallel in a large cluster, it needs to rely

This article is written in the spark1.6.2 version.Because fine mode has an excessive impact on short-task performance, the coarse mode is used for scheduling. some of the main issues: 1.6 Version start dynamic allocation not available For example, such as Spark-shell programs, idle time resources long-term occupancy but can not be released, resulting in low resource utilization. Multiple executor cannot be started on a single slave Only one executor can be started for each

Mesos and Kuberneteshttp://dockone.io/article/956 I firmly believe that their use will grow faster in the next year, so it is time to review the summary and prepare for 2016 years. I would like to discuss the current situation of Mesos and kubernetes and enumerate the strengths and weaknesses that will allow you to understand the concept of cluster manager.Mesos and KubernetesBefore I start, I'd like to tak

Practical application scenarios of Mesos [Editor's note] the content in this article comes from a question on stackoverflow. The questioner wants to know which use cases Mesos has in actual use, twitter engineers answered questions from the perspectives of container orchestration, resource utilization, priority and resource preemption, and service operation. I tried to find out why users are using

My experience in running Docker on Mesos My technology Stack As I wrote in this blog, I want to share with you how to use docker containers in a single cluster to run analysis jobs. In Zions, we are studying Apache Mesos running on the MapR platform and MapR-FS. My goal is to try to build a ubiquitous computing platform. For analysis, I run Spark and Myriad (more development is required for MapR and other p
