Mike Percy commented on FLUME-1238:
-----------------------------------
Seems like having a separate thread that watches the open files should do the
trick. It can also keep track of rollInterval.
I'll take a stab at this one.
> Support active rolling of files created by HDFS Event Sink

> The HDFS Event Sink uses lazy rolling for closing files that are being
> written to. This results in many files being open for longer than their
> expected roll-interval if they are not actively written to and can even last
> in open state until the sink shuts down.
> It will be preferable to have these files roll proactively rather than
> waiting for a write to trigger the roll.
