[jira] Created: (HADOOP-3284) [HOD] hod does not follow symlinks correctly

[HOD] hod does not follow symlinks correctly
--------------------------------------------

                 Key: HADOOP-3284
                 URL: https://issues.apache.org/jira/browse/HADOOP-3284
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hod
    Affects Versions: 0.16.3, 0.16.2, 0.16.1, 0.16.0
         Environment: rhel 5.1
            Reporter: Jim Huang


On the local file system, we have a mount point /opt, inside /opt, we have symlink called "0" -> .
HOD is installed in /opt/0/hod.
All the directory values inside the hodrc file utilize the /opt/0/hod values.  
When trying to allocate the cluster, it gave the following result:

$ hod allocate -d mycluster -n 5
CRITICAL - No job found, ringmaster failed to run.
CRITICAL - Cannot allocate cluster /homes/jim/mycluster

No other additional error messages was produced.
To fix this issue, the symlink 0 -> . was removed.  
An actual directory called 0 was created in its place and hod was put inside of it.  
After the cluster was able to be allocate.
