Subject [jira] [Created] (AMBARI-3136) Reduce the size of ExecutionCommand entity
Date Fri, 06 Sep 2013 20:57:51 GMT
Myroslav Papirkovskyy created AMBARI-3136:
---------------------------------------------

             Summary: Reduce the size of ExecutionCommand entity
                 Key: AMBARI-3136
                 URL: https://issues.apache.org/jira/browse/AMBARI-3136
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.4.0
            Reporter: Myroslav Papirkovskyy
            Assignee: Myroslav Papirkovskyy
             Fix For: 1.4.1
         Attachments: AMBARI-3136.patch

Currently, each ExecutionCommandEntity stores the whole config blob. This is a severe duplication
of data as tagged configuration information is already available as immutable entry.
We need to reduce the footprint of ExecutionCommandEntity by storing only configuration tags.
The tags can be replaced with actual configuration value when the command is handed off to
the agent.
We need to ensure that when Ambari is upgraded and there is a mix of ExecutionCommandEntity
instances with and without embedded config - it works.
