The discontinuation of support won't affect the following versions of the framework: 3.5, 4.5.2, 4.6 and 4.6.1. Net Framework, these supported versions are defined as components instead of independent products by Microsoft.
Components are supported for the lifecycle of the operating system they are available for which means that the listed .
Master will also update the slaves (that have active tasks of the framework) via Update Framework Message.
The authentication part is straightforward because a framework with updated ‘principal’ should authenticate with the new ‘principal’ before being allowed to re-register.
The ‘authenticated’ map already gets updated when the framework disconnects and reconnects, so it is fine. Slave only uses ‘Framework Info.user’ when launching a new executor if and only if the ‘Command Info.user’ is not specified on task/executor itself.
So any new task/executor launches on such slaves will ignore the updated Framework Info (e.g, framework checkpointing).
A slave will only get the updated Framework Info when the framework’s task is launched on the slave and the slave doesn’t know about the framework i.e., there are no active tasks/executors belonging to the framework on the slave. Allow the frameworks to update their Framework Info without having to restart masters or slaves or tasks/executors.
A failed over framework doesn’t get new offers until it re-registers with its (possibly updated) Framework Info.
Currently, there is no mechanism for the Allocator to reject such updates because all its API methods return ‘void’ and hence are expected to succeed.
Net Framework is installed on devices they manage or use. All available versions will be supported by Microsoft until the operating system reaches its end of support. He is passionate about all things tech and knows the Internet and computers like the back of his hand.
Additional information about the move, including changes in newer versions of the .
In other words, the updated Framework Info should be properly reconciled across the cluster in a seamless fashion. The framework will create a new Mesos Scheduler Driver with the updated Framework Info (likely after a framework process restart).
Under the covers the driver will re-register with the Master with the updated Framework Info.
Net Framework that may impact applications and code, are provided on the official Microsoft Dotnet blog linked in the first paragraph of this article.
