Ajay -----Original Message----- From: Harsh J [mailto:ha...@cloudera.com] Sent: Friday, February 17, 2012 12:11 PM To: hdfs-user@hadoop.apache.org Subject: Re: Replication Ajay, Some of your client programs are creating files with replication factor 3 explicitly (or are using a default configuration instead of your configuration, which sets it to 3). The dfs.replication factor config isn't cluster-wide as I mentioned before, and a client may override it (or override via a direct integer value via the Java API) at will. You need to fix this from the client side.
