Examples of com.cloudera.flume.agent.MasterRPC

com.cloudera.flume.agent.MasterRPC
This interface manages function calls between a Flume node and some set of masters. Implementing classes should translate these calls into rpc package-specific methods. Any method which throws an IOException is interpreted as having lost connection to all available masters.
