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:-)

1- How can I replicate an existing file by an application?
[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.
Regards,
Uma
