>          Components: native
>    Affects Versions: 2.7.0
>         Environment: Solaris
>            Reporter: Martin Walsh
>            Assignee: Martin Walsh

> The POSIX subclass in NativeIO contains the following constants that are not defined
in POSIX:
> O_ASYNC, O_FSYNC, O_NDELAY
> Stat.S_IFWHT
> These constants are not used within Hadoop, as far as I could tell.  As they are not
part of the POSIX specification, they should be removed as part of an effort to create portable
code.
