Because Hadoop is still in its early stage of rapid development, and it is open-source, its version has been very messy. Some of the main features of Hadoop include: Append: Supports file appending. If you want to use HBase, you need this feature. RAID: to ensure data reliability, you can introduce verification codes to reduce the number of data blocks.
