What are the differences between the Linux file system and Hadoop distributed file system?

Answer»

Linux file system

*****************

  1. You can STORE the Linux file under a single disk
  2. You can store the small file in a disk if the file size is more than the disk size then you can not store.
  3. Each block size is 4 KB.
  4. If the machine is down, we can not able to get the data and failover chances are more

HADOOP  Distributed file system

*****************************

  1. A distributed file system can be stored in a logical layer which is created on ONE or more disk.
  2. You can store files as larger as you can, you need to add more disk to the logical layer
  3. Each block size is 64MB/128MB/256MB as per the Hadoop version and you can customize the size too.
  4. Data is replicated in different nodes. Clients are able to read the data if any node fails. Failover is less
