Answer» NFS is Network File System and HDFS is HADOOP DISTRIBUTED File System. The various differences between the two are as follows. NFS
| HDFS
| Only small amount of data can be stored and processed with NFS
| Large amount of data or big data can be stored and processed with HDFS.
| NFS STORES data on a single dedicated machine or a DISK of a dedicated network machine. These data files can be ACCESSED by the clients over the network
| HDFS stores data in a distributes manner. In other words, data is stores on many dedicated machines or network computers
| NFS is not fault tolerant and data can be lost if there is some failure is caused. This data can’t be recovered in future.
| HDFS is fault tolerant and data can be easily recovered in case of any failure caused in nodes.
| There is no data redundancy that can occur in NFS as all the data get stored on a single dedicated machine.
| Data redundancy can be point of concern here because of the replication of same data files across the multiple dedicated machines.
