Hadoop HA 集群 提交mr任务不成功 44C

Job job_1504179588390_0001 failed with state FAILED due to:

Application application_1504179588390_0001 failed 2 times due to Error launching appattempt_1504179588390_0001_000002. Got exception: java.net.ConnectException: Call From localhost.localdomain/127.0.0.1 to localhost:43660 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

  • 其他一切正常,就是无法执行mr程序
  • 推断是将任务提交到本地了而不是集群
