Hari Shreedharan commented on FLUME-1946:
-----------------------------------------
I am planning to start looking into this. I intend to do:
* New format for the channel, with sync marker support
* Mirror the events on write.
I am thinking about working on a one-pager to come up with a requirements spec.

> Project: Flume
> Issue Type: Bug
> Components: File Channel
> Reporter: Mike Percy

> It would be great to investigate changes to the FileChannel that enable it to
> tolerate failure of one or more disks in a group of data directories across
> disks without losing data. This involves implementing support for some form
> of mirroring at the software level, as well as appropriate recovery routines.
