John George updated HDFS-1821:
------------------------------
Description:
TEST SETUP
Using attached sample hdfs java program that illustrates the issue.
Using cluster with Kerberos enabled on cluster
# Compile instructions
$ javac Symlink.java -cp `hadoop classpath`
$ jar -cfe Symlink.jar Symlink Symlink.class
# create test file for symlink to use
1. hadoop fs -touchz /user/username/filetest
# Create symlink using file context
2. hadoop jar Symlink.jar ln /user/username/filetest /user/username/testsymlink
# Verify owner of test file
3. hadoop jar Symlink.jar ls /user/username/
-rw-r--r-- username hdfs /user/jeagles/filetest
-rwxrwxrwx usern...@xx.xxxx.xxxxx.xxx hdfs /user/username/testsymlink
RESULTS
1. Owner shows 'usern...@xx.xxxx.xxxxx.xxx' for symlink, expecting 'username'.
2. Symlink is corrupted and can't removed, since it was created with an invalid
user
------------------------
Sample program to create Symlink
FileContext fc = FileContext.getFileContext(getConf());
fc.createSymlink(target, symlink, false);
---------------------------------------
