>          Issue Type: Bug
>          Components: native
>    Affects Versions: 2.4.1
>         Environment: System z/Linux
>            Reporter: David Villegas
>            Assignee: David Villegas

> In org.apache.hadoop.io.nativeio.NativeIO.java, the posix_fadvise flag parameter is hardcoded
to the most common values in fcntl.h.
> However, not all architectures use the same values (in this case, System z/Linux) A better
approach would be to not make assumptions about fcntl.h values (or any other system constants).
> This bug results in calls to posix_fadvise failing in zLinux.
