Thank you Is there a method which list for me files with n replicas or I myself must implement it? If so just FileSystem#getFileBlockLocations() can help me? Thanks in advance:-)

[Uma Ans] : you can just set the replication factor high. use the following API for resetting the replication factor from application. FileSystem#setReplication 2- Where is the number of replicas for each file saved? I mean how can I find out number of replicas for a specific file? Regards [Uma Ans] : FileSystem#getFileBlockLocations should give you the locations where it stored.
