libhadoop is all or nothing
---------------------------

Key: HADOOP-7405
URL: https://issues.apache.org/jira/browse/HADOOP-7405
Project: Hadoop Common
Issue Type: Bug
Components: native
Affects Versions: 0.20.203.0, 0.23.0
Environment: Everything not Linux
Reporter: Allen Wittenauer
Priority: Blocker


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.
