Storage Node Vs Compute Node

Compute Node

  • This is the computer or machine where your actual business logic will be executed.
  • The compue node mainly focussed on RAM and CPU


Storage Node

  • This is the computer or machine where your file system reside to store the processing data. In most of the cases compute node and storage node would be the same machine.
  • The storage node maily focussed on block storage.


What are the restrictions for Key and Value Class

  1. The key and value classes have to be serialized by the framework. To make them serializable Hadoop provides a Writable interface. 
  2. As you know from the java itself that the key of the Map should be comparable, hence the key has to implement one more interface WritableComparable.

I am practicing Python programming. This post is you can write logic to calculate factorial in function. This function you can call it a user-defined function. The function name is 'factorial.py'. In real-time, you can write a program in a file and run it in python console. The main task of a developer is to create functions for the reusable code. They call these functions whenever they need. Factorial calculation program for supplied input value. Factorial Logic in Python I have completed this logic in 3 steps. Write factorial.pyImportExecute it Write Factorial.py  Here you need to define a function. Use 2 for loops, and write your logic. This is done on LInux operating system. You can also try on Linux.
After, ESC command Use, :wq to come out of the module. Import Factorial.py Go to Python console, using 'python' command. Use import factorial.py command.


Execute Factorial.py  >>> factorial.fact(5) It will show the result of factorial. Bottom line  Factorial o…
