com.betfair.cougar.transport.api.ExecutionCommand
A command to execute an operation with the specified arguments, and to be notified of the result.
org.apache.ambari.server.agent.ExecutionCommand
Execution commands are scheduled by action manager, and these are persisted in the database for recovery.
