> WebHdfs client connections use sockets with fixed timeouts of 60 seconds to connect, and 60 seconds for reads.
> This is a problem because I am trying to use WebHdfs to access an archive storage system which can take minutes to hours to return the requested data over WebHdfs.
> The fix is to add new configuration file options to allow these 60s defaults to be customised in hdfs-site.xml.
> If the new configuration options are not present, the behavior is unchanged from before.
