[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.
