-----------------------------------
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.
