Description

the $HADOOP_CONF_DIR is exist in the $CLASSPATH
and the dfs.replication is set to 3 with the following in hadoop-site.xml
<property>
<name>dfs.replication</name>
<value>1</value>
</property>

The file's replication is 3 when it be put into hadoop.

I think the reason is :
there is a hardcoding in the src\contrib\fuse-dfs\src\fuse_dfs.c　

line 1337
if ((fh->hdfsFH = (hdfsFile)hdfsOpenFile(fh->fs, path, flags, 0, 3, 0)) == NULL) {
line 1591
if ((file = (hdfsFile)hdfsOpenFile(userFS, path, flags, 0, 3, 0)) == NULL) {

the fifth parameter is a hardcoding when call the function of hdfsOpenFile.

It is should set to 0. It is as follows.
line 1337
if ((fh->hdfsFH = (hdfsFile)hdfsOpenFile(fh->fs, path, flags, 0, 0, 0)) == NULL) {
line 1591
if ((file = (hdfsFile)hdfsOpenFile(userFS, path, flags, 0, 0, 0)) == NULL) {
