Re: Replication Factor Modification
Replication factor is per-file, and is a client-side property. So, this is

1. Change the replication factor of all existing files (or needed ones):

$ hadoop fs -setrep -R <value> /

2. Change the dfs.replication parameter in all client configs to the
desired <value>
