NiFi: Flowfile retries

avatar
Expert Contributor

For e.g. PutHDFS processor, if the failure relationship is connected to itself

1) How to control the number of retries of a single flowfile?

2) I see "FlowFile Expiration" can be used to expire the message (meaning discard the Flowfile content if it cannot be reprocessed within a specified period of time). Is there a way to retain the FlowFile content after specified number of retries, that is to persist on a different channel say local file system (PutFile) and perhaps be able to send email notification ?

Check out this template as it will do exactly what you are looking for:

Retry_Count_Loop.xml

Just feed your failure relationship in to this process group and the output from this process group back to your processor.

Thanks,

Matt

The "sleep" command is a linux command. The command simply runs and waits the configured amount of time before exiting. Typically this command in linux is found under /usr/bin/sleep. I noticed above is missing the leading "/" . But if it is still not found, try searching your linux for it. It is installed as part of the linux "coreutils" rpm.
