Steve Loughran commented on SLIDER-186:
---------------------------------------

The AM would need to know this ... I propose having a file that is created once; if it does not exist then the cluster is deemed to be "new". 

If you delete the cluster: tough.

This could be a JSON file with some information 
{code}
createtime: string
{code}

> If its known to the application that the instance is being created for the first time (as opposed to thawed) then the application can perform some one time clean-up or setup if needed.
> AppMaster can provide the flag to a provider. The agent provider can make the flag available to the app package during INSTALL command and the application package can use the flag as appropriate.
