当我在Hive中执行简单查询(类似select * from tablex)时,我遇到了问题

Stage-1 map = 0%,reduce = 0%

我尝试使用直线和HUE执行该查询,在两种情况下情况相同。

有人可以帮忙吗?

This issue can be because of the following reasons

  1. Your cluster is not having enough resources to launch a container.
  2. Your job is submitted to a resource pool or queue without proper resources.

Check the total resources in the cluster. If enough resources are available, check the queue in which the job got submitted and check the resources allocated to that queue.

These details can be checked from the resource manager UI.
