全部。我运行 hive 查询运行到 97%，异常显示 org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException: No lease on sth。

任何人都可以解释发生此错误的原因吗？这是一个单用户 Hive 集群环境。

先感谢您。

您的 Hive 查询是否创建并行 MR 作业？我遇到了同样的问题，发现：LeaseExpiredException：HDFS 上没有租约错误：

当工作结束时，他删除 /data/work/ 文件夹。如果并行运行的作业很少，则删除也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会引发此异常

设置 hive.exec.max.dynamic.partitions=100000; 设置 hive.exec.max.dynamic.partitions.pernode=100000;
