Hari Shreedharan commented on FLUME-2595:
-----------------------------------------
Looks like the patch was not updated based on the comments. If you do so, I can
commit this to 1.6. Also, I think we should grab the exclusive lock, then set
open = false.
> Add option to checkpoint on file channel shutdown

>
> Restarting a File channel based agent can take very long, a few hours to
> evens days in some cases. The reason being the slow replay performance.
> By having the file channel checkpoint on shutdown, this long replay can
> avoided as there will be nothing to replay on startup.
> A small hit (a few seconds perhaps) will be observed on shutdown to perform
> the checkpoint.
