kubectl versions Error: exec plugin is configured to use API version client.authentication.k8s.io/v1alpha1

Asked 2022-Mar-28 at 09:41

I was setting up my new Mac for my eks environment. After the installation of kubectl, aws-iam-authenticator and the kubeconfig file placement in default location. I ran the command kubectl command and got this error mentioned below in command block.

My cluster uses v1alpha1 client auth api version so basically i wanted to use the same one in my Mac as well.

I tried with latest version (1.23.0) of kubectl as well, still the same error. Whereas When i tried to do with aws-iam-authenticator (version 0.5.5) I was not able to download lower version.

Can someone help me to resolve it?

I have the same problem

You're using aws-iam-authenticator 0.5.5, AWS changed the way it behaves in 0.5.4 to require v1beta1.

It depends on your configuration, but you can try to change the K8s context you're using to v1beta1

Otherwise switch back to aws-iam-authenticator 0.5.3 - you might need to build it from source if you're using the M1 architecture as there's no darwin-arm64 binary built for it

I believe this is an issue due to the mongoDB version is not compatible with the latest version of MongoDB Compass.

Solution: Downgraded MongoDB Compass version to 1.28.4 (1.28.4).

We have a bunch of microservices based on Spring Boot 2.5.4 also including spring-kafka:2.7.6 and spring-boot-actuator:2.5.4. All the services use Tomcat as servlet container and graceful shutdown enabled. These microservices are containerized using docker.

How to map function directly over list of lists?

Asked 2021-Dec-26 at 15:38

I have built a pixel classifier for images, and for each pixel in the image, I want to define to which pre-defined color cluster it belongs. It works, but at some 5 minutes per image, I think I am doing something unpythonic that can for sure be optimized.

How can we map the function directly over the list of lists?

Answered 2021-Jul-23 at 07:41

Just quick speedups:

You can omit math.sqrt()
Create dictionary of colors instead of a list (that way you don't have to search for the index each iteration)
use min() instead of sorted()

You are better off avoiding serializable isolation level. The way the serializable guarantee is provided is often deadlock prone.

If you can't alter your stored procs to use more targeted locking hints that guarantee the results you require at a lesser isolation level then you can prevent this particular deadlock scenario shown by ensuring that all locks are taken out on ServiceChange first before any are taken out on ServiceChangeParameter.

One way of doing this would be to introduce a table variable in spGetManageServicesRequest and materialize the results of

How to check Databricks cluster for Log4J vulnerability?

Asked 2021-Dec-14 at 20:03

I'm using a Databricks cluster version 7.3 LTS with Scala 2.12. This version does use Log4J.

The official docs say that it uses Log4J version 1.2.17. Does this mean I do not have this vulnerability? And if I do, can I manually patch it on the cluster or do I need to upgrade the cluster to the next LTS version?

...

ANSWER

Answered 2021-Dec-13 at 17:00

As you wrote most Databricks clusters use 1.2.17 so it is different version and version affected by vulnerability is not used by Databricks.

Only one problem is when you install different version by yourself on the cluster. Even when you installed affected version you can mitigate the problem by setting Spark config in cluster advanced config as below:

QUESTION

How to run the predicted probabilities (or average marginal effects) for individuals fixed effects in panel data using R?

Asked 2021-Oct-26 at 18:47

These are three different ways to run an individual fixed effect method which gives more or less the same results (see below). My main question is how to get predictive probabilities or average marginal effects using the second model (model_plm) or the third model(model_felm). I know how to do it using the first model (model_lm) and show an example below using ggeffects, but that only works when i have a small sample.

As i have over a million individual, my model only works using model_plm and model_felm. If i use model_lm, it takes a lot of time to run with one million individuals since they are controlled for in the model. I also get the following error: Error: vector memory exhausted (limit reached?). I checked many threads on StackOverflow to work around that error but nothing seems to solve it.

I was wondering whether there is an efficient way to work around this issue. My main interest is to extract the predicted probabilities of the interaction residence*union. I usually extract predictive probabilities or average marginal effects using one of these packages: ggeffects,emmeans or margins.

...

ANSWER

Answered 2021-Oct-22 at 17:46

This potential solution uses biglm::biglm() to fit the lm model and then uses emmeans::qdrg() with a nuisance specified. Does this approach help in your situation?

No vulnerabilities reported

Install cluster

Simply add cluster into your app. Then when you are deploying or starting your app, export the following environment variables. Now start as many servers as you like and DDP traffic will be sent to each of the instances randomly. You can also remove instances anytime without affecting the cluster or your app.
Let's see how you could setup Cluster in a practical scenario. BulletProof Meteor is already running Cluster so I will show you an excerpt of its setup. (I've changed some information for the educational purposes). We have four Servers and three of them are Balancers. This is how they are structured. I'm using Meteor Up to deploy and here's a sample configuration file. With Meteor Up, you don't need to expose CLUSTER_ENDPOINT_URL. It'll automatically do that by itself. Make sure you install the latest version of Meteor Up. We'll use cloudflare for DNS and SSL setup.

Support

Cluster has the multi-core support as well. You can run your Meteor app utilizing all the cores in your server as follows:. Make sure you've added the meteorhacks:cluster package.
