hi all, I have been using ambari to manage our cluster of hadoop, now i met a problem that i can’t push command to agents , there always some exception like:
Traceback (most recent call last): File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py", line 35, in <module> BeforeAnyHook().execute() File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 219, in execute method(env) File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py", line 29, in hook setup_users() File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/shared_initialization.py", line 41, in setup_users groups = params.user_to_groups_dict[user], File "/usr/lib/python2.6/site-packages/resource_management/core/base.py", line 154, in __init__ self.env.run() File "/usr/lib/python2.6/site-packages/resource_management/core/environment.py", line 158, in run self.run_action(resource, action) File "/usr/lib/python2.6/site-packages/resource_management/core/environment.py", line 121, in run_action provider_action() File "/usr/lib/python2.6/site-packages/resource_management/core/providers/accounts.py", line 44, in action_create if not self.user: File "/usr/lib/python2.6/site-packages/resource_management/core/providers/accounts.py", line 94, in user return pwd.getpwnam(self.resource.username) TypeError: getpwnam() argument 1 must be string, not None Error: Error: Unable to run the custom hook script ['/usr/bin/python2', '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py', 'ANY', '/var/lib/ambari-agent/data/command-3281.json', '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY', '/var/lib/ambari-agent/data/structured-out-3281.json', 'INFO', '/var/lib/ambari-agent/tmp'] i find there is a jira bug (https://issues.apache.org/jira/browse/AMBARI-13401 <https://issues.apache.org/jira/browse/AMBARI-13401>) Is this a bug of ambari? how can I fix this issue? thanks juntao
