Balu Vellanki updated FALCON-1728:
----------------------------------
Assignee: (was: Balu Vellanki)
> Process entity definition allows multiple clusters when it has output Feed
> defined.
> ------------------------------------------------------------------------------------
>
> Key: FALCON-1728
> URL: https://issues.apache.org/jira/browse/FALCON-1728
> Project: Falcon
> Issue Type: Bug
> Components: process
> Affects Versions: 0.9
> Reporter: Balu Vellanki
> Priority: Critical
>
> Process XSD allows user to specify multiple clusters per process entity. I am
> guessing this would allow a user to run duplicate instance of the process on
> multiple clusters at the same time (I do not really see a need for this).
> When the process has an output feed defined, you can have duplicate process
> instances writing to same feed instance, causing data corruption/failures.
> The solution is to
> 1. Do not allow multiple clusters per process. Let the user define a
> duplicate process if user wants to run duplicate instances.
> OR
> 2. Allow multiple clusters, but only when there is no output feed defined.
> [~sriksun] please let me know if there is any other reason for allowing
> multiple clusters in a process.
