Apache Mesos Essentials

By: Dharmesh Kakadia

Overview of this book

<p>Apache Mesos is a cluster manager that provides efficient resource isolation and sharing across distributed applications, or frameworks. It allows developers to concurrently run the likes of Hadoop, Spark, Storm, and other applications on a dynamically shared pool of nodes. With Mesos, you have the power to manage a wide range of resources in a multi-tenant environment.</p> <p>Starting with the basics, this book will give you an insight into all the features that Mesos has to offer. You will first learn how to set up Mesos in various environments from data centers to the cloud. You will then learn how to implement self-managed Platform as a Service environment with Mesos using various service schedulers, such as Chronos, Aurora, and Marathon. You will then delve into the depths of Mesos fundamentals and learn how to build distributed applications using Mesos primitives.</p> <p>Finally, you will round things off by covering the operational aspects of Mesos including logging, monitoring, high availability, and recovery.</p>

Upgrade


Mesos has a very frequent release cycle. Upgrading it is relatively simple:

  • Install the new master binaries

  • Restart the master process

  • Install the new binaries on the slave

  • Restart slave processes

  • Upgrade the schedulers by linking to the new Mesos library

  • Restart the schedulers

If required, the executors can be upgraded by linking the new Mesos library. As we have seen in Chapter 6, Understanding Mesos Internals, tasks survive slave processes and executor restarts. If a Mesos release needs an upgrade of the underlying operating system kernel, restarting the master and slave machines might be required. Mesos upgrade documentation (http://mesos.apache.org/documentation/latest/upgrades/) provides more information for upgrading to different versions.

Mesos infrastructure also requires you to maintain different frameworks so that they're up to date. For some frameworks, such as Spark, the upstream Spark project itself maintains Mesos schedulers and executors. For most frameworks, which are ported...
