> Key: HADOOP-10962
> URL: https://issues.apache.org/jira/browse/HADOOP-10962
> Project: Hadoop Common
> Issue Type: Bug
> Components: native
> Affects Versions: 2.4.1
> Environment: System z/Linux
> Reporter: David Villegas
> Assignee: David Villegas
> Fix For: 2.6.0
>
> Attachments: HADOOP-10962.patch
>
>
> 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.
