###
### where:
###   <username> and <password> represent account credentials used to run
###   Slider services as Windows services.

### HADOOP_NODE_INSTALL_ROOT environment variable to a location were
### you'd like Hadoop installed.
###

###
### To uninstall previously installed Single-Node cluster run:
