You can set the block replication in your hdfs-site.xml configuration file by specifying the property dfs.replication with replication value.
Moreover once the remote table dump is completed, you can run the replication for your individual or group of table by, hadoop fs –setrep –w [int REPLICATION_FACTOR] -R /path/to/your/directory/or/file Cheers!
