Subject the balance of datanodes
Date Thu, 02 May 2013 07:33:35 GMT
Hi,
I put 6.7G datas to the HDFS. It showed that all the datas were put to one datanode of the
cluster.
I thought the datas would be put to all the datanodes.
My hadoop version is 1.0.4, and my dfs.replication value is 1.

Why this happen?Is it necessary for me to do some configuration about the balance?

The result is:
