> Even we can use "dfs -put" or "dfs -cp" to move data between swift and secured HDFS, it will be impractical for moving huge amount of data like 10TB or larger.
> Current Hadoop code will result in :"java.lang.IllegalArgumentException: java.net.UnknownHostException: container.swiftdomain" 
> Since it does not support token feature in SwiftNativeFileSystem right now, it will be reasonable that we override the "getCanonicalServiceName" method like other filesystem extensions (S3FileSystem, S3AFileSystem)
