Juhani Connolly commented on FLUME-935:
---------------------------------------
Looks like it was a problem on my end... Let eclipse autoimport the wrong
ChannelException.
That being said, I still don't think that using something as generic as
Exception is a good idea, and that the doXYZ classes probably shouldn't be
throwing any checked exceptions other than Interrupted
> Create abstract implementations of basic channel/transaction semantics

> Project: Flume
> Issue Type: Improvement
> Components: Channel
> Affects Versions: v1.0.0
> Reporter: Peter Newcomb

> Priority: Minor
> Fix For: v1.1.0

>
> Correctly executing or checking the state transitions for channels and
> transactions is nontrivial. It would be helpful to have a correct
> implementation of each that can be used either directly or as a reference
> when creating new channels or clients of channels.
> Specifically, on the client side it would be nice to package the try {
> begin() ... commit() } catch { rollback() } finally { close() } code, with
> all the appropriate exception propagation and logging code, so that it need
> not be repeated constantly.
> On the channel side, it'd be nice to have a packaged implementation of the
> implied ThreadLocal semantics of the Transaction class, along with
> Preconditions checking to make sure that clients follow the try { begin() ...
> commit() } catch { rollback() } finally { close() } pattern.
