Ashish Jain commented on GERONIMO-5027:
---------------------------------------

Here is what I have understood

Redeploy in geronimo is handled by a set of STOP, UNLOAD, UNINSTALL, INSTALL. LOAD, START
operations. In case of farming as there are set of nodes we will have to obtain the JMX info
of each of the nodes so as to get a kernel for each of the nodes. Any of the deploy commands
is executed by obtaning the meta data and than calling up
the execute for the meta data. In case of farming install and uninstall are taken care of
by ConfigurationStore.install/uninstall.

In case of redeploy configuration manager is being used which is obtained through COnfigurationUtil.getConfigurationManager(kernel).

There were various ways I have tried to achieve this for farming

1) To get the meta data for deploy and undeploy in redeploy, which is not possible due to
private constructors.
2) Extend the DeployTool to take up this case but this does not seem to be correct to be specific
for one funtionality.
3) Get the NodeInfo's in RedeployCommand and with some modifications to artifact call up a
series of STOP, UNLOAD, UNINSTALL, INSTALL. LOAD, START operations.

There can be many other approaches which could be used of which I am not aware of..

Comments please??
