What Is Rack Awareness Algorithm. Rack awareness is having the knowledge of cluster topology or more specifically how the different data nodes are distributed across the racks of. The rack awareness algorithm comes into play to identify data nodes with the shortest distance available for read or write. Let’s understand this with an example. For example, hdfs block placement will use rack awareness for. In short, rack awareness is a concept of selecting the datanodes closer to namenode for reading/write operations to maximize performance by reducing network traffic. In the above image, we have 3 different racks in our hadoop cluster each rack contains 4 datanode. This concept of choosing the closest data node for serving a purpose is rack awareness. For example, hdfs block placement will use rack awareness for. Now suppose you have 3 file blocks (block 1, block 2, block 3) that you want to put in this data node.
