HTTPParser | HTTPParser is an HTTP parser for Swift | Reactive Programming library

Since I could not figure the problem out I switched to httpx and all worked just fine and my problem was solved in minutes. Be careful about the timeout, you should set a value that makes sense for your requirements. I can highly recommend httpx: https://www.python-httpx.org/

This will solve your problem, you need to have all the code wrapped in if else statements so that it can always terminate successfully with only one possible path through the code.

Make sure you are using express.urlencoded({ extended: true }) middleware, as shown in the documentation otherwise req.body will be undefined.

The output of console.log(req.body.device) you posted is probably the result of outdated code running, because that is what you would normally get from running console.log(req). I've tried running your code and the console output works correctly https://www.anyfiddle.com/p/robalb/sih511dv

Also this is not relevant to the question, but you can get rid of the javascript code in your template by changing the type of the form button from type="text" to type="submit" like this

That’s caused by the res.end('Error'), which gets always executed. Try to put it into an else clause, or put a return before each res.end(…)

As in the comments, in client side, you need to specify content type explicitly.

for example:

As mentioned on the comments, this is due to res.end being called multiple times, the simplest solution for you would either to return after each res.end or adjust your conditions:

To send chunked encoding messages in node, use the POST method:

Yes, it is possible, I have done it countless times, several years ago when those sandbox machines were actually maintained. They are not, anymore, though since the recommendation is to use cloud-hosted Hadoop solutions like AWS EMR, Google DataProc, or Azure HDInsights.

The errors you are seeing in Ambari are expected. Nothing starts, by default.

You need to actually start the services in this order before you can even use Hive.

• HDFS
  • NameNode
  • DataNode
• YARN
  • NodeManager
  • ResourceManager
• Zookeeper
• Hive
  • Metastore
  • HiveServer2

If you really just want something resembling "Hadoop + SQL", then install Presto/Trino, Spark, or Flink locally on your Mac
