Host not returned with getApplicationAttempts API

[AJAY GUPTA]

Hi,

I want to print the Host received in applicationAttemptReport of all
attempts when yarnClient.getApplicationAttempts() API is called. I see that
the host received is NULL whereas other fields have information. Is this a
bug or only I am seeing this behaviour?


application_attempts {

  application_attempt_id {

    application_id {

      id: 2

      cluster_timestamp: 1481851584221

    }

    attemptId: 1

  }

  host: ""

  rpc_port: 0

  tracking_url: "http://localhost:8088/proxy/application_1481851584221_0002/
"

  diagnostics: ""

  yarn_application_attempt_state: APP_ATTEMPT_RUNNING

  am_container_id {

    app_attempt_id {

      application_id {

        id: 2

        cluster_timestamp: 1481851584221

      }

      attemptId: 1

    }

    id: 1

  }

  original_tracking_url: "localhost:59636"
