Code Issues Proposed changes

Fix bugs when install HDFS 

1. use ~/ instead of $DEST/
2. use "__slashplaceholder__" instead of @
3. add changed PATH to the first line of ~/.bashrc
3. Fix the auto exit issue in start_hdfs.sh, make sure all hdfs services start
4. Add test_hdfs method after hdfs start
