Scott Carey commented on AVRO-513:
----------------------------------
bq. Not sure about an interrupt signal being intercepted, or not being
delivered. But I think it's possible that the interrupt occurs between the
check on "done" and the call to take(), so the call to take() would go ahead
and cause a deadlock.
I think all Java blocking I/O and queue operations check the interrupted status
on the thread before sleeping/waiting. Or more precisely --the JVM checks it
before the thread yields, and will throw the interrupted exception if the flag
is set.

> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Doug Cutting

> Fix For: 1.4.0
>
> Attachments: AVRO-513.patch, AVRO-513.patch

>
> The Java mapreduce API added in AVRO-493 requires reducers implementations to
> explicitly detect sequences of matching data.
> Rather the reduce method might better look something like:
> void reduce(Iterator<IN>, Collector<OUT>);
> Where all equal values are passed in a single call.
