Answer / Tanzeem Akhter
The default block size of 128MB in HDFS was chosen due to several reasons: n1. Network latency: A larger block size helps reduce the overhead caused by network communication.n2. Storage efficiency: It allows for better utilization of storage resources as data is written in larger chunks.n3. Processing efficiency: Larger blocks can be processed faster compared to smaller ones.
