Jojy Varghese commented on MESOS-3798:
--------------------------------------
Preliminary investigation shows that the junk characters are written after the
os::nonblock(fd) in the write function.
> io::write(fd, const string&) api writes junk sometimes

> This was noticed during registry client test( please see MESOS-3773).A brief
> summary :
> 1. open a file with flags " O_WRONLY | O_CREAT | O_TRUNC | O_CLOEXEC" and
> mode "S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH)",
> 2. Call write(fd, string).
> This causes junk to be written every once in a while to the beginning of the
> file.
