# This script is used as NetworkTopology Mapping Script in TestRackawareEnsemblePlacementPolicyUsingScript.java TestSuite
# It just maps HostAddress to rack depending on the last character of the HostAddress string
# for eg. 
#       127.0.0.1    - /1
#       127.0.0.2    - /2
#       199.12.34.21 - /1
# This script file is used just for testing purpose
# rack 0 returns script error (non-zero error code)
