[jira] [Resolved] (HADOOP-7405) libhadoop is all or nothing

     [ https://issues.apache.org/jira/browse/HADOOP-7405?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Allen Wittenauer resolved HADOOP-7405.
--------------------------------------

    Resolution: Won't Fix

Hadoop is not focused on portability.

>          Issue Type: Bug
>          Components: native
>    Affects Versions: 0.20.203.0, 0.23.0
>         Environment: Everything not Linux
>            Reporter: Allen Wittenauer

> As a result of a ton of new code in libhadoop being added in 0.20.203/0.22, a lot of features that used to work no longer do reliably.  The most common problem is native compression, but other issues such as Mac OS X's group support broke as well.  The native code checks need to be refactored such that libhadoop.so should report what it supports rather than having the Java-side assume that if it loads, it is all supported.  This would allow us to stub routines until they've been vetted, removing the chances of such regressions appearing in the future.
