Subject [jira] [Created] (AMBARI-119) Add database to map cluster-role to current working directory
Date Mon, 31 Oct 2011 21:01:33 GMT
Add database to map cluster-role to current working directory
-------------------------------------------------------------

                 Key: AMBARI-119
                 URL: https://issues.apache.org/jira/browse/AMBARI-119
             Project: Ambari
          Issue Type: New Feature
          Components: agent
    Affects Versions: 0.1.0
         Environment: Python
            Reporter: Eric Yang
            Assignee: Eric Yang
             Fix For: 0.1.0


Proposed directory structure layout:

{noformat}
$prefix/$cluster-$role/stacks
                      /config
                      /logs/
                      /data/disk-*/
                      /pkgs/hadoop-*.tar.gz
                      /config/hadoop/core-site.xml
{noformat}

One optimization that Owen proposed is to make the directory structure shorter for client.

{noformat}
$prefix/$cwd/stacks
            /config
            /logs
            /data/disk-*/
            /pkgs/hadoop-*.tar.gz
            /config/hadoop/core-site.xml
{noformat}

Action send by controller will contain "current working directory", which agent will record
the cluster and role mapping to current working directory.
