所有。我运行一个配置单元查询运行到97％，并且异常显示org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException:暂时没有租约。
谁能解释这个错误的原因？
这是一个单用户Hive群集环境。
先感谢您。

最佳答案
您的配置单元查询是否创建并行MR作业？
我有同样的问题，发现:LeaseExpiredException: No lease error on HDFS:
作业结束后，他删除了/ data / work /文件夹。如果并行运行的作业很少，则删除操作还将删除另一个作业的文件。实际上我需要删除/ data / work /。
换句话说，当作业尝试访问不再存在的文件时，抛出此异常
