问题 I am trying to create a template for a Kubernetes cluster having 1 master and 2 worker nodes. I have installed all the pre-req software and have run the kubeadmn init on my master node. But when i try to run the kubeadmn join which i get as an output of the init command i am getting an error.

问题 I have one application that we deploy on a cluster. The cluster might have 2 or 4 JVMs as per the environment. The application has same CamelContext which we are deploying on all the JVMs. Hence, all the JVMs have same routes. For FTP routes, that is good as it makes it competitive and only 1 JVM gets the files. However, while using timer based operation to fetch from DB, I see that all the JVMs read the same set of records and do the same job. What I want is, if one route picks it up, the

问题 I haven't worked with distributed computing before, but I'm trying to integrate mpi4py into a program in order to parallelize a for loop on a compute cluster. This is a pseudocode of what I want to do: for file in directory: Initialize a class Run class methods Conglomerate results I've looked all over stack overflow and I can't find any solution to this. Is there any way to do this simply with mpi4py, or is there another tool that can do it with easy installation and setup? 回答1: In order to
