open() does not work

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
The c code like this,

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
int main(int argc, char **argv) {
  int fp;
  fp= open("/mnt/hdfs/fusetest",O_CREAT | O_RDWR , 0664);
  if(fp<0){
    printf("error creating...\n");
    return -1;

  }
}
2. compile the code with gcc and run the executable.

What is the expected output? What do you see instead?
I expect the file can be created successfully.

What version of the product are you using? On what operating system?
hadoop-0.20.2 on ubuntu 9.04 amd64. Kernel version 2.6.28.10
