Allen Wittenauer resolved HDFS-901.
-----------------------------------
Resolution: Won't Fix
> Fedora jdk install creates circular symlinks, causes test-c++-libhdfs not to
> build
> ----------------------------------------------------------------------------------

> Key: HDFS-901
> URL: https://issues.apache.org/jira/browse/HDFS-901
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: build
> Affects Versions: 0.20.1
> Environment: Fedora 2.6.26.8.fc8; hadoop 0.20.1; java 1.6.0_17
> Reporter: robert Cook
> Priority: Minor
>
> installed hadoop; needed javac; installed jdk
> export JAVA_HOME=/usr/java/jdk1.6.0_17
> ant clean
> ant
> ant -Dcompile.c++=true -Dlibhdfs=true test-c++-libhdfs
> -------------------------------------------------------------------------------

> -------------------------------------------------------------------------------
> tracked bug down as follows:
> for some reason, install of jdk creates a symlink from within jdk directory
> to existing jre impl jre1.6.0_17 and a symlink from within jre directory to
> jdk.
> I suspected the recursion likely messed up a "find" somewhere; deleted
> symlink in jdk then
> ant clean
> ant
> ant -Dcompile.c++=true -Dlibhdfs=true test-c++-libhdfs
> BUILD and TEST ran successfully then
> just to be sure I put the symlink back; reran above; same failure
