you have to include the hdfs-site.xml and hdfs-default.xml. Because those
two files tell you where is the namenode and what is the operation port.

Yes, if you delete a directory, its contents are recursively deleted.
If you do not want that to happen (i.e. you want a protective
measure), use http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/fs/FileSystem.html#delete(org.apache.hadoop.fs.Path,%20boolean)
with false. And it will never delete a directory.
Sort of like rm vs. rm -r on *nix.

yes this will delete the entire directory and its contents (assuming
that user running the code has the permission to delete the directory)
