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

BUILD FAILED
note: insertion of /usr/java/jdk1.6.0_17/jre1.6.0_17/lib/i386/server is spurious
-------------------------------------------------------------------------------
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
