<div>Hi Aldrin,</div>

<div>&nbsp;</div>

<div>I still have problem getting started. So I write up a little bit more.</div>

<div>&nbsp;</div>

<div>I have a master process that runs first. Then I have multiple other processes that
are supposed to run only after the master process has finished. The processes are external
processes.</div>

<div>&nbsp;</div>

<div>So a typical flow would be that the master starts. The other processes don&#39;t
start because the master process is still running and has not completed. Once the master process
completes, the other processes can start.</div>

<div>&nbsp;</div>

<div>I hope this helps and you can give me another hint of how to do that.</div>

<div>&nbsp;</div>

<div>Rgds,</div>

<div>&nbsp;</div>

<div>Uwe</div>

<div>Welcome to the community!</div>

<div>&nbsp;</div>
If you are looking for one process to be kicked off by another, there is a related processor
to ExecuteProcess called ExecuteStreamCommand and I believe should what you are looking for.&nbsp;
ExecuteStreamCommand will accept FlowFiles from incoming connections and use those to drive
processing.&nbsp; In this case, you could have whatever stimulus you are waiting for drive
follow on execution.

<div>&nbsp;</div>

<div>If this does not solve what you are looking for, could you please provide some
additional details about your needs that are unmet by the ExecuteStreamCommand approach?</div>

<div>&nbsp;</div>

<div>Thanks!</div>

<div>Hello,</div>

<div>&nbsp;</div>

<div>I am new to Nifi and have a general question for the ExecuteProcess processor.</div>

<div>&nbsp;</div>

<div>Is it possible with Nifi to run a process and have a second process wait until
the first one finished? How would I do that? It looks like though that this processor does
not allow for an incomming connection, so I wonder if there is a different strategy I could
take.</div>

<div>&nbsp;</div>

<div>Tahnks for your valuable help.</div>
