yarn | A simple asynchronous routing pattern for Node.js | Reactive Programming library

I am trying to proxy requests from my containerized React application to my containerized Flask application.

I was starting the application using npm start (in Docker), and I did not have any issues proxying requests. However, I learned that npm start is not a good way to proceed in production.

Following the advice here: Run a React App in a Docker Container , I am able to start my containerized production React, but now the requests are not proxied.

Within the React app, all requests are handled with axios and are formatted: "/api/v1/endpoint". It seems that others have had issues between "http://localhost:80/api/v1/endpoint" and "/api/v1/endpoint". I do not believe this is my issue, unless it arises only in the production environment.

I have also tried changing my "proxy" address in package.json to the location of the dockerized flask container, and later to the name of the docker container, but I have not been able to make either solution work.

If anyone can provide guidance on launching a containerized, production React app that proxies requests to a backend container, please advise.

I am open to using a different server, if the procedures in "Run a React App in a Docker Container" need to be updated.

I have looked these solutions:

I have a project with E2E tests setup with Playwright + TS-Jest. To organize my tests I use Page Object Model. Structure looks like that:

I wanted to use TypeScript paths option in tsconfig.json to clean up the imports both in test files as well as in POM classes. After some trial and error I came up with the following config files:

I am new to Spark and am trying to run on a hadoop cluster a simple spark jar file built through maven in intellij. But I am getting classnotfoundexception in all the ways I tried to submit the application through spark-submit.

My pom.xml:

I am trying to extract the application Id.

As an example i need to extract

application_1621858977521_0074

from the following log line

I have setup a small size Hadoop Yarn cluster where Apache Spark is running. I have some data (JSON, CSV) that I upload to Spark (data-frame) for some analysis. Later, I have to index all data-frame data into Apache SOlr. I am using Spark 3 and Solr 8.8 version.

In my search, I have found a solution here but it is for different version of Spark. Hence, I have decided to ask someone for this.

Is there any builtin option for this task. I am open to use SolrJ and pySpark (not scal shell).

I'm setting up a new project with nodejs, express, typescript, and babel. So I use babel for faster transpile typescript code and etsc for types checking

When I writing code, I'd like to the application applied changes automatically without me manually restart the application. My solution is running babel cli for transpile code with nodemon. My script is like this

I have an Apache Kylin container running in docker. I was getting a Java heap space error in map reduce phase so I tried updating some parameters in Hadoop mapred-default.xml file. After making the changes, I restarted the container but, when I go to Yarn ResourceManager Web UI and then to Configuration:

An xml file is opened, looking like this:

However my new values for the properties that I set inside the mapred-default.xml are not here, it is showing the old values for those properties... Does anyone have any idea why that is happening and what I should do to make it register the new values? I tried restarting the container, but it didn't help...

Here is some info about the machine I'm using:

• Node v14.17.0
• Electron v13.1.2
• Win 10 21H1
• Yarn 2.4.2

I'm trying to get my project here at: https://github.com/Cokaps/GenZOC working but I've ran to this issue:
When I run electron-forge start, it shows an error here:
