Mike Percy commented on FLUME-1946:
-----------------------------------
Yeah I agree it would be risky to do surgery on the file channel in place.
Let's make a new version to add major new features such as this one.
Also +1 on a format converter. It would be nice to get rid of the FC Hadoop dep
while maintaining an upgrade path.

> 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.
