At the moment, that's something that can be > scripted or that can be done using multiple InvokeHttp processors but it > requires a bit of work. > Even though it is not really in the "NiFi way of thinking", it would be > interesting to have a processor with the following parameters: > - NiFi REST API URL > - Username > - Password > - Processor UUID (with expression language) > - Action to perform (START, STOP, START/STOP, STOP/START) > - Sleep duration (between the START and STOP calls when action is START/STOP, > or STOP/START) > That would be helpful in use cases like: > - start a workflow based on another workflow > - start a processor not accepting incoming relationship based on a flow file > - restart a processor to "refresh" its configuration when the processor > relies on configuration files that could be changed > - have a "start once" behavior -- This message was sent by Atlassian JIRA (v6.4.14#64029)
