我正在尝试将一个大文件（32gb）复制到hdfs中。我在hdfs中复制文件从来没有遇到过任何问题，但这些文件都比较小。我在用 hadoop fs -put <myfile> <myhdfsfile> 高达13.7 gb，一切正常，但我有一个例外：

hadoop fs -put * /data/unprocessed/

当我检查日志文件（在我的namenode和datanodes上）时，我看到文件上的租约被删除了，但是没有指定原因。根据日志文件，一切都很顺利。以下是我的namenode日志的最后几行：

有人知道这件事吗？我查过了 core-default.xml 以及 hdfs-default.xml 对于我可以覆盖的财产，这将延长租赁或左右，但找不到一个。
