                 Key: HADOOP-3523
                 URL: https://issues.apache.org/jira/browse/HADOOP-3523
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hod
    Affects Versions: 0.18.0
            Reporter: Hemanth Yamijala
            Assignee: Hemanth Yamijala
            Priority: Blocker
             Fix For: 0.18.0


HADOOP-3483 addressed the issue where a dead cluster could be reallocated 
without having to issue warnings to users to clean up the directory themselves, 
provided the job is completed. It missed one case, where the job no longer 
exists in the Torque queue. When tried in that case, HOD fails with a bad error 
message:
ERROR - qstat error: exit code: 153 | signal: False | core False
CRITICAL - op: allocate hod-clusters/test 3 failed: <type 
'exceptions.TypeError'> 'NoneType' object is unsubscriptable

This should be addressed to avoid user concerns.
