To change the replication factor (RF) of a file already present in HDFS, you can use the 'setrep' command with the Hadoop FileSystem API. The syntax is: hadoop fs -setrep [-R] <replication-level> <path> where <replication-level> is the new replication factor and <path> is the path to the file or directory.
