Hadoop is not in the classpath/dependencies

To resolve the issue of Hadoop not being in the classpath or dependencies, you can follow these steps:

1. Make sure you have Hadoop installed on your system. You can download it from the Apache Hadoop website.

2. Check if the Hadoop installation directory is correctly set in the HADOOP_HOME environment variable. If not, set it to the directory where Hadoop is installed.

3. If you are using a build tool like Maven or Gradle, add the Hadoop dependencies to your project's configuration file (pom.xml for Maven or build.gradle for Gradle). Here is an example for Maven:

<dependencies>
    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-client</artifactId>
        <version>${hadoop.version}</version>
    </dependency>
</dependencies>

Replace `${hadoop.version}` with the desired version of Hadoop.

4. If you are not using a build tool, you can manually add the Hadoop JAR files to your project's classpath. You can find the necessary JAR files in the Hadoop installation directory under the `share/hadoop` and `share/hadoop/lib` folders.

After following these steps, rebuild your project or restart your application, and Hadoop should be available in the classpath/dependencies.
