Disadvantages of Hadoop distributed file system (HDFS):
In distributed file system ,it is limited in its power. The files in an NFS volume all reside on a single machine. This will create some problems.
1.It does not gives any reliability guarantees if that machine goes down.
Ex:-by replacing the files to other machine
2.All the reliants must go to this machine to retrieve their data. This can overload the server if a large no. of clients must be handled.
3.clients need to copy the data to their local machines before they can on it.
