Distributed File Management system

As the volume of data is increasing and the scope of one operating system is not available, it is allocated to more disks managed by the operating system, but is not easily managed and maintained, so a system is urgently needed to

Manage files on multiple machines, this is the Distributed file Management system.

is a file system that allows files to be shared across multiple hosts on a network, allowing multiple users on multiple machines to share files and storage space.

Permeability, which is actually the action of accessing the file over the network, is seen by the program and the user as if it were accessing the local disk in general.

Fault-tolerant, even if some nodes are offline in the system, the system can continue to operate without data loss as a whole.

There are many distributed file management systems, and HDFs is just one of them. See http://www.cnblogs.com/zlslch/p/5683055.html. Applies to the case that writes multiple queries at once, does not support concurrent write situations, and small files are inappropriate.
