Verifying Connection Status

The status light next to the connection indicates whether the CWA Master is connected to the MapReduce server. If the 
light is green, the MapReduce server is connected. 

A red light indicates that the master cannot connect to the MapReduce server. MapReduce jobs will not be submitted 
without a connection to the MapReduce server. You can only define jobs from the Client if the connection light is green. 

If the light is red, you can test the connection to determine the problem. Right-click the connection and select
