[jira] [Commented] (NIFI-8963) Request NIFI API - wrong client_id

["Matt Gilman (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-8963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17391560#comment-17391560 ] 

Matt Gilman commented on NIFI-8963:
-----------------------------------

[~Wogno] You are correct. The clientId and revision help ensure that when any client submits a request they are acknowledging the latest configuration helping to prevent a scenario where client1 could override client2 configuration because their request was sent after the other but before they refreshed locally. In order to use it you either need to supply the current revision OR be the client that last made a change. The latter case helps clients that want to submit many requests without necessarily waiting for each to process and return. The solution isn't foolproof obviously as clients could share the same clientId but then they would not gain the protection the API was designed to provide.

> Hello,
> As I understand *client_id and version* is available to avoid same client api changed the state of component with the same version.
>  
> But sometime when I call NIFI API about the status of component, the "client_id" key is not available, so I can't change the status of compoent, even if I used *uuidgen* to create a new client_id before request a change status.
> What is the better way to be sure that NIFI API accept request with the correct *client_id and revision?*
> Because I got this error :
> {code:java}
