Resolution: Duplicate
> Framework should not allow the "uuid" attribute to be removed.
> --------------------------------------------------------------

> Key: NIFI-1182
> URL: https://issues.apache.org/jira/browse/NIFI-1182
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Labels: beginner, newbie
>
> The framework should guard against removing the "uuid" attribute. Code
> already exists to do this, but it appears that a bug exists that does allow
> the "uuid" attribute to be removed if the removal is done with a regular
> expression.
> I.e., StandardProcessSession.removeAllAttributes(FlowFile, Pattern) does not
> protected against this, though
> StandardProcessSession.removeAllAttributes(FlowFile, Set) and
> StandardProcessSession.removeAttribute(FlowFile, String) do protect against
> it.
> We need to ensure that all attribute removal methods protect against this.
