LeaseExpiredException在蜂房(LeaseExpiredException in

所有。我运行一个蜂巢查询运行97％和异常表明org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException：对某事没有租期。

任何人都亲切地解释为什么发生这个错误的原因吗？这是一个单用户配置单元集群环境。

先感谢您。

Answer 1:

请问您的蜂巢查询创建并行MR工作？我有同样的问题，结果发现： LeaseExpiredException：HDFS上没有租用错误：

当作业结束他删除/数据/工作/文件夹。如果一些工作并行运行的缺失也将删除另一份工作的文件。其实我需要删除/数据/工作/。

换句话说，当作业尝试访问文件，这些文件不再存在这种异常被抛出

Answer 2:

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