Answer / Vikalp Chauhan
The Distributed Cache feature in Hadoop allows applications to put additional files into the distributed cache on each node where the job runs. This feature can be useful when you need files that are not part of your input or output data, but are needed by the application for processing. Instead of reading these files from HDFS every time, they are cached on the nodes, reducing network traffic and improving performance.
