> Purge FutureReturnValueIgnored warnings from error prone
> --------------------------------------------------------
>
> Key: HBASE-27222
> URL: https://issues.apache.org/jira/browse/HBASE-27222
> Project: HBase
> Issue Type: Improvement
> Components: netty
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-4
>
>
> We used to introduce a FutureUtils to purge the FutureReturnValueIgnored
> warnings in the async client implementation, to make sure we catch the
> exception from the callback.
> For netty, we could apply the same trick. And there is another problem for
> netty that channel.write and some other methods will also return a
> ChannelFuture but usually we just do nothing on it, this will generated a
> FutureReturnValueIgnored warning too. We could add a logging listener to log
> the errors if any.
