Most asked AKTU PYQ questions from Unit 3

  1. Q2c. Explain the core concepts of HDFS, including NameNode, DataNode, and the file system namespace. How do these components work together to manage data storage and replication in Hadoop clusters? (10 marks, 2023-24)
  2. Q4a. Describe the Hadoop Distributed File System (HDFS). How does HDFS manage the storage and replication of data across a distributed cluster of machines? (10 marks, 2023-24)
  3. Q2b. Discuss Hadoop Distributed File System (HDFS), and how does it work. (10 marks, 2023-24)
  4. Q5a. Demonstrate the design of HDFS and concept in detail. (10 marks, 2021-22)
  5. Q2c. Discuss the design of Hadoop Distributed File System (HDFS) in detail. (10 marks, 2017-18)
  6. Q6a. Explain Master slave and peer-peer replication in detail. (10 marks, 2017-18)
  7. Q1b. Define the Hadoop Distributed File System (HDFS). How is it different from traditional file systems? (2 marks, 2024-25)
  8. Q1g. Explain Hadoop distributed file system. (2 marks, 2017-18)
  9. Q5a. Explain how HDFS stores, reads, and writes files. Describe the sequence of operations involved in storing a file in HDFS, retrieving data from HDFS, and writing data to HDFS. (10 marks, 2023-24)
