Jayush Luniya updated AMBARI-21645:
-----------------------------------
    Description: 
Installing an mpack can install a new stack or update and existing stack. On an mpack install we need to do the following dynamically so as to not require restarting the ambari server or agent. 

# Reload the stack manager to refresh the stacks REST API endpoint
# Refresh all the resource files (i.e. recreate archive.zip for service package, hooks etc. )
# Refresh the agent file cache.
