-------------------------------------

             Summary: Exception during after-INSTALL hook (HDP 2.0.6) if stack version contains letters
                 Key: AMBARI-9812
                 URL: https://issues.apache.org/jira/browse/AMBARI-9812
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server, stacks
    Affects Versions: 2.0.0
            Reporter: Romain Lenoel
            Priority: Critical


When trying to install a stack named "2.2.XXX" which simply extends HDP-2.2 (and so 2.0.6), the following exception is raised :
{code}
Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/after-INSTALL/scripts/hook.py", line 35, in <module>
    AfterInstallHook().execute()
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 208, in execute
    method(env)

  File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/after-INSTALL/scripts/shared_initialization.py", line 26, in setup_hdp_install_directory
    if params.hdp_stack_version != "" and compare_versions(params.stack_version_unformatted, '2.2') >= 0:
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/functions/version.py", line 73, in compare_versions
    return cmp(_normalize(version1, desired_segments=max_segments), _normalize(version2, desired_segments=max_segments))
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/functions/version.py", line 34, in _normalize
    return [int(x) for x in v_list]
ValueError: invalid literal for int() with base 10: 'XXX'
{code}

The exception raises because of the use of the unformatted version name in the following code {code}File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/after-INSTALL/scripts/shared_initialization.py", line 26, in setup_hdp_install_directory
    if params.hdp_stack_version != "" and compare_versions(params.stack_version_unformatted, '2.2') >= 0{code}
