Correct answer: Azure Data Lake Storage Gen2.
Why this is the answer
Azure Data Lake Storage Gen2 is the correct choice because it is built on Azure Blob Storage and offers a hierarchical namespace, which is essential for HDFS compatibility. It provides high-throughput, low-latency access to data, making it ideal for big data analytics workloads like those found in Hadoop environments. Azure NetApp Files provides high-performance file storage but is not designed for direct HDFS compatibility. Azure Data Share is a data sharing service, not a storage solution for HDFS. Azure Table storage is a NoSQL key-value store and does not support the HDFS interface.
