From: Jeff Zhang To: general@hadoop.apache.org Content-Type: text/plain; charset=UTF-8 Hi all I change the replication of file by using command : bin/hadoop setrep But when I use fsck to check the status of the file, it always shows that the one replica of this file is missing. I know that setrep command only change the metadata of NameNode, so when will it affect the data node eventually ? And Can I force the procedure ? -- Best Regards Jeff Zhang
