Question 42/72
Identify two features of the Hadoop Distributed File System (HDFS). (Choose two.)
Correct Answer: A,D
Explanation/Reference:
HDFS is a distributed file system that provides high-performance access to data across Hadoop clusters.
Like other Hadoop-related technologies, HDFS has become a key tool for managing pools of big data and supporting big data analytics applications.
The Hadoop framework, which HDFS is a part of, is itself is mostly written in the Java programming language, with some native code in C and command line utilities written as shell scripts.
