-------------------------------------
Summary: 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
Assignee: 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.
