Subject [jira] [Created] (AMBARI-2010) Tasks do not timeout for failed hosts
Date Wed, 24 Apr 2013 00:55:15 GMT
Siddharth Wagle created AMBARI-2010:
---------------------------------------

             Summary: Tasks do not timeout for failed hosts
                 Key: AMBARI-2010
                 URL: https://issues.apache.org/jira/browse/AMBARI-2010
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.3.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 1.3.0
         Attachments: AMBARI-2010.patch

We have seen that the tasks do not timeout within X minutes, where X is a predictable number
like 10 minutes. This becomes relevant when task are created for dead nodes.

Example, I have killed a host after registration and then hit Deploy for that host. Since
the host is unreachable, we depend on task timeout to clean the pending actions, this happens
but takes a very long time.

One possible fix is to fast fail tasks for hosts in UNKNOWN state
