Noah Watkins commented on HADOOP-7097:
--------------------------------------
I tracked down the problem in the trunk. It comes down to an old usage of
HADOOP_CORE_HOME vs HADOOP_COMMON_HOME. That seems to fix it, and
HADOOP_CORE_HOME isn't returned by any grep, so, is it special?

> java.library.path missing basedir
> ---------------------------------
>
> Key: HADOOP-7097
> URL: https://issues.apache.org/jira/browse/HADOOP-7097
> Project: Hadoop Common
> Issue Type: Bug
> Components: build, native
> Affects Versions: 0.23.0
> Environment: Ubuntu 10.10
> Reporter: Noah Watkins
> Priority: Blocker
> Fix For: 0.23.0

>
> My Hadoop installation is having trouble loading the native code library. It
> appears from the log below that java.library.path is missing the basedir in
> its path. The libraries are built, and present in the directory shown below
> (relative to hadoop-common directory). Instead of seeing:
> /build/native/Linux-amd64-64/lib
> I would expect to see:
> /path/to/hadoop-common/build/native/Linux-amd64-64/lib
> I'm working in branch-0.22.
