[jira] [Commented] (FLUME-2850) FileChannel should allow take operation when minimumRequiredSpace runs out

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.

> 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.
