I have been asked this question in an online quiz.

My question comes from Introduction to HDFS in portion HDFS – Hadoop Distributed File System of Hadoop

Answer 1

Correct answer is (a) HDFS is not suitable for scenarios requiring multiple/simultaneous writes to the same file

To elaborate: HDFS can be used for storing archive data since it is cheaper as HDFS allows storing the data on low cost commodity hardware while ensuring a high degree of fault-tolerance.
