Hari Shreedharan commented on FLUME-2613:
-----------------------------------------
Updating events in the channel would be really tricky/difficult, since that
would require the entire remaining part of the file to be re-written and would
also need to adjust for the file reaching max length etc. Also, the checkpoint
would have to be re-written. I don't think that is something we want to worry
about. A validator can write out the file to a different file if it needs to.
We should also allow the validator to parse command line options, since it
might be useful to make custom changes based on config.
> Tool/script for deleting individual message from queue

> We had a situation where one of our Flume agents got stuck on a message due
> to unexpected format. To get things moving again, I stopped the Flume agent,
> moved the file backed channel data out of the way and re-started the Flume
> agent. I'd like to pop the bad message from the queue data on disk and
> ideally there would be a recommended tool/script.
