Hadoop 每当我运行配置单元查询时，它都会被那些在MapReduce上工作的操作卡住

它在这里卡住了。

mapreduce.framework.name

已设置为本地，但您似乎正在使用。。。否则，您必须转到跟踪url以找出它被卡住的原因

Query ID = niraj_20201108170818_6dd4f715-f1b9-4b31-a184-75c60417a080
Total 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=<number>
In order to limit the maximum number of reducers:
  set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
  set mapreduce.job.reduces=<number>
