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...
