Unable to find class: ava.util.HashMap

[Bright Chen]

Hi,
I tried to launch the “AdsDimensionsDemoFast"(the class name is 
AdsDimensionsDemoPerformant) application of example/dt-demo/dimensions in 
cluster and the application failed.
I check the dt.log and found following exception( the class is 
“ava.util.HashMap”, I am not sure was the error of log or the required class 
name was wrong )
Anyone has any idea?

thanks
Bright
