Description

In PIG-4958, I had to resort to

DAGClient client = new DAGClientImpl(appId, dagID, new TezConfiguration(conf), null);

This is not good as DAGClientImpl is a internal class and not something users should be referring to. Tez needs to have an API to give DAGClient given the appId, dagID and configuration. This is something basic like JobClient.getJob(String jobID).
