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=

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
