------------------------------------

    Attachment: HADOOP-4877.txt.trunk

Here is a patch for trunk. My only thoughts are that for truncate, it might be more uniform if the original file replication number was kept.

> the $HADOOP_CONF_DIR is exist in the $CLASSPATH

> <property>
>   <name>dfs.replication</name>
>   <value>1</value>
> </property>
> The file's replication is 3 when it be put into hadoop.
