当我尝试运行涉及mapreduce的hive命令时，我收到以下错误，请帮我解决这个问题：
hive (hiveclass)> create table companies2 as select * from companies;
WARNING: Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.
Query ID = hduser_20161105115631_5868a474-de3c-4cc9-80f9-40a6fac60fa2
Total jobs = 3
Launching Job 1 out of 3
Number of reduce tasks is set to 0 since there's no reduce operator
Starting Job = job_1478325284966_0010, Tracking URL = http://ubuntu:8088/proxy/application_1478325284966_0010/
Kill Command = /home/hduser/hadoop/bin/hadoop job -kill job_1478325284966_0010
在kill命令之后，什么也没发生。然后我必须给ctrl + c并退出hive shell。
