Starting HiveServer2
Hive history file=/tmp/hive/hive_job_log_93d99855-d258-4c9e-b0ad-a1fad756d589_377643780.txt
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=
In order to set a constant number of reducers:
set mapred.reduce.tasks=
Starting Job = job_1393569994072_0007, Tracking URL = http://hnbc-c:8088/proxy/application_1393569994072_0007/
Kill Command = /usr/lib/hadoop/bin/hadoop job -kill job_1393569994072_0007
这个问题也遇到过，因为之前平台一直启用spark跑数据，
后来突然遇到需要用MR执行的sql 都是 卡住不动，也不报错。
/var/log/hive后台日志也没报任何错误信息。
最后采用直接方式，重启集群解决，然后就可以了。
楼主如果有找到最根本原因，也请爆下，谢谢
