I did so. I even rm -rf on dfs's dir and do namenode -format before starting my dfs. hadoop fsck reports the default replication is 1, avg. block replication is 2.9x after I wrote some data into hbase. The underlying dfs is used by hbase.

Hmm... as far as I understand the hadoop FileSystem, you can specify # of replication when creating a file. But I did not find hbase use it, correct? Regards, Rong-En Fan > > St.Ack >
