Hi guys: Im getting this very odd error in my sun / ubuntu / hadoop run.
- im not running a hadoop cluster here, just some local FS java hadoop
map/r jobs.
- The exception Im getting on FileSystem.get(conf) is
"java.lang.ClassNotFoundException: com.sun.security.auth.UnixPrincipal"
Here are my specs :
vagrant@precise64:~/Development/workspace/pisae$ grep 'hadoop' ./ivy.xml
*<dependency org="org.apache.hadoop" name="hadoop-core" rev="0.20.205.0"/>
*
