Bob Hansen commented on HDFS-9643:
----------------------------------
In {{ReaderGroup::GetLiveReaders()}}, you need to trim the readers_ member once
you're done with {{remove_if}}. {{remove_if}} only shuffles the live elements
forward and returns the new end; you need a subsequent {{readers_.erase(newEnd,
readers_.end());}}
What does the comment "no-op to keep method PV qualified in parent" mean?
I don't see an implementation of {{DataNodeConnection::Cancel()}}. Did I miss
something?
