-------------------------------------
Hi [~James C],
yes, those are one type of the warnings, also I see warnings due to
-Wunused-lambda-capture though after checking a few instance of this warning,
they not seems to be related to this patch, though I just vaguely checked, but
most likely they were there before as well.
With the patch applied, I do not see inconsistent-missing-override warnings,
and the include helped as well to get over the compile error.
> libhdfs++: Use hdfs::IoService object rather than asio::io_service

> At the moment the hdfs::IoService is a simple wrapper over asio's io_service
> object. I'd like to make this smarter and have it do things like track which
> tasks are queued, validate that dependencies of tasks exist, and monitor
> ioservice throughput and contention. In order to get there we need to use
> have all components in the library to go through the hdfs::IoService rather
> than directly interacting with the asio::io_service. The only time the
> asio::io_service should be used is when calling things like asio::async_write
> that need an io_service&. HDFS-11884 will be able get rid of those remaining
> instances once this work is in place.
