[jira] [Commented] (NIFI-5758) Duplicate Variables

["Joseph Rosado (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-5758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16693661#comment-16693661 ] 

Joseph Rosado commented on NIFI-5758:
-------------------------------------

The problem is when I make a change to the variable at the parent level, those changes are not replicated downstream to embedded process groups.  In fact, the embedded process groups will reference it's local variable as per the design; thus overriding the parent.  As a result, I need to manually delete all scoped variables from embedded process groups whenever I import a process group from the Registry.  Unfortunately, this negates the concept of a "global" variable.  Instead, we should have the option to choose whether a variable should be scoped to embedded process groups.

> We have a process group with variables defined for the entire flow.  However, the variables are duplicated in each nested process group.  Therefore, making it difficult to manage, and identify issues. (see attached)
