---------------------------------
Summary: 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
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.
