> libhdfs++: Use hdfs::IoService object rather than asio::io_service
> ------------------------------------------------------------------
>
> Key: HDFS-13403
> URL: https://issues.apache.org/jira/browse/HDFS-13403
> Project: Hadoop HDFS
> Issue Type: Task
> Reporter: James Clampffer
> Assignee: James Clampffer
> Priority: Critical
> Attachments: HDFS-13403.000.patch
>
>
> 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.
