> The existing HDFS tool wrappers (src/hdfs/hdfs.hpp) are synchronous. They use os::shell to shell out the 'hadoop' commands. This makes it very hard to be reused at other locations in the code base.
> The URI fetcher HDFS plugin will try to re-use the existing HDFS tool wrappers. In order to do that, we need to make it asynchronous first.
