Exception in thread main java lang UnsatisfiedLinkError org apache hadoop io nativeio NativeIO$Windo

**Introduction:**

**Main Content:**

So, let's dive into the details. The "UnsatisfiedLinkError" is a Java exception that occurs when the JVM (Java Virtual Machine) cannot find a native library or method that's being called. In this case, the error message is complaining about a missing method in the NativeIO class of Apache Hadoop.

The reason for this error is usually due to a mismatch between the version of Hadoop you're using and the version of the native libraries on your system. You see, Hadoop relies on these native libraries to interact with the operating system, and if they're not compatible, it throws an exception.

Imagine you're trying to plug in a USB device into a port that doesn't exist on your computer. That's kind of what's happening here - the Java code is trying to access a method that doesn't exist or isn't compatible with the native libraries.

Now, let's talk about why this error happens specifically with Apache Hadoop. Hadoop is designed to work on multiple platforms, including Windows, Linux, and macOS. However, some of its components are written in C++ and rely on native libraries to interact with the operating system. When you're running Hadoop on a Windows machine, it tries to access these native libraries, which might not be present or compatible.

**Key Takeaways:**

To summarize, here are the key points to remember:

* The "UnsatisfiedLinkError" occurs when Java can't find a native library or method.
* This error usually happens due to version mismatches between Hadoop and native libraries.
* Hadoop relies on native libraries to interact with the operating system.
