Subject [jira] [Created] (FALCON-2091) Add an admin command to sync definitions of Prism and Falcon servers

Pallavi Rao created FALCON-2091:
-----------------------------------

             Summary: Add an admin command to sync definitions of Prism and Falcon servers
                 Key: FALCON-2091
                 URL: https://issues.apache.org/jira/browse/FALCON-2091
             Project: Falcon
          Issue Type: Bug
            Reporter: Pallavi Rao


In Falcon distributed mode, some times when a user updates an entity definition, it gets updated
in certain Falcon Servers and/or Prism. This causes the definition to go out of sync between
the Falcon servers and Prism, as each one of them has their own store. This causes some of
the subsequent entity commands to fail. Currently, there is no way to fix this (unless one
hacks around the falcon store and restarts the server). 

Although, we should identify the root cause of such errors and fix those. Not all causes can
be covered and it causes the user to land in a sticky situation.

The proposal is to add an admin command (sync definition or something like that), so, that
a common definition (preferably, what is there on prism), gets pushed to all servers and the
ConfigurationStore gets updated. That way the entity on the servers and Prism are all in sync.
