             Summary: Configurable location for deployment scanner marker files
                 Key: WFLY-2503
                 URL: https://issues.jboss.org/browse/WFLY-2503
             Project: WildFly
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Domain Management
            Reporter: Brian Stansberry


Add marker-dir and marker-dir-relative-to attributes to the deployment scanner resource. These control where the marker files are written, with the default being the dir being scanned itself.

The idea here is to allow sharing of a deployments/ dir by letting users redirect the markers to some other location.

To store in a server-specific subdir of deployments (making the markers still fairly accessible the user):

{code}
<deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"
marker-dir="deployments/${jboss.node.name}"
marker-dir-relative-to="jboss.server.base.dir"
/>
{code}

To store the markers in the data dir, out of sight, out of mind:

{code}
<deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"
marker-dir="deployment-scanner-markers"
marker-dir-relative-to="jboss.server.data.dir"
/>
{code}

This all sounds simple enough, but anyone looking into it *must* assume this will be a highly complex task, as the scanner itself is very complex and assumes that the deployments and the markers are in the same dir. Extremely extensive test coverage will be required.
