Hari Shreedharan commented on FLUME-2850:
-----------------------------------------
In theory, I agree. But remember that takes also do take up disk space. It
would be interesting to add an additional config, but the implementation is
likely to be non-trivial.
> FileChannel should allow take operation when minimumRequiredSpace runs out

> Key: FLUME-2850
> URL: https://issues.apache.org/jira/browse/FLUME-2850
> Project: Flume
> Issue Type: Bug
> Components: File Channel
> Affects Versions: v1.6.0
> Reporter: Tycho Lamerigts
>
> In the status quo, when minimumRequiredSpace runs out, FileChannel closes
> itself and thereby prevents flume from ever self-recovering. Instead, manual
> action is needed to free up some disk space. If FileChannel would only block
> put operations and would still allow take operations then flume could
> self-recover, assuming some sinks will eventually succeed in draining the
> channel. Also, it would lead to fewer dropped events overall.
