Description

TestRefreshCallQueue and TestGenericRefresh use the same hard-coded port number (54222) leaving them susceptible to 'port in use' errors with parallel testing as seen here.

Error Message

Problem binding to [localhost:54222] java.net.BindException: Address already in use; For more details see:  http://wiki.apache.org/hadoop/BindException
