@jvrao the main explanation is that we already call shutdownNow if the pool
does not end execution within 1 minute.
In my personal usecases I usually kill bookies (kill -9) and do not wait
for graceful shutdown

>
> Several unit tests are taking very long time to complete (eg:
> {{BookieLedgerIndexTest}} taking ~10 minutes).
> The reason is that these tests are playing with the ZK quorum shutting it
> down and after the test succeeds, the shutdown phase is taking long time,
> since we try to do graceful shutdown with 1min wait time.
> I think is better to interrupt immediately the garbage collector thread when
> shutting down the bookie.
