Subject Replication problem of HDFS
Date Wed, 05 Sep 2007 08:58:15 GMT

According the reference of
HDFS(http://lucene.apache.org/hadoop/hdfs_design.html),
a file in the HDFS will be split into one or more blocks and these blocks
are stored in 
a set of Datanodes. 

I put(set replication=1) a 2GB data set to a 5-nodes cluster, but found only
the 
namenode increase the block numbers, others nodes keep the same value. It
means
all blocks copied to the namenode, none to datanodes. Is it correct?
