Devaraj Das commented on AMBARI-119:
------------------------------------
BTW I just committed a change where the controller sets the workDir component
in the Actions. I added a field workDirComponent to the Action class.
Before running any action, the working directory should be set to
<ambari-prefix>/workDirComponent. The install/createDirStructure should also
use this as the destination directory.
> Add database to map cluster-role to current working directory

> 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.
