Explain how does hadoop classpath plays a vital role in stopping or starting in hadoop daemons?..

Answer / Vijay Saxena

Hadoop Classpath is crucial for managing the libraries and dependencies required by Hadoop daemons. When starting or stopping Hadoop daemons, the classpath specifies the location of these dependencies. This ensures that all necessary files are available, making the startup or shutdown process successful. By default, the classpath includes core-site.xml, hdfs-site.xml, mapred-site.xml, yarn-site.xml, and the Hadoop common jars.nnFor stopping a daemon, the classpath helps in locating the shutdown script which executes the necessary steps to stop the service. Similarly, during startup, the classpath directs the daemon to the necessary configuration files and libraries needed for operation.
