hadoop - Hadoop dfs put 失败

Question

当进程在夜间从 shell 脚本（由 Jenkins 运行）触发时，我收到此错误（hadoop dfs -put），但是，如果我稍后手动尝试，它运行正常。

put: Lease mismatch on /shared/file1.tsv._COPYING_ owned by DFSClient_NONMAPREDUCE_-2031300157_1 but is accessed by DFSClient_NONMAPREDUCE_-1375175076_1

13/08/07 07:11:39 ERROR hdfs.DFSClient: Failed to close file /shared/epg/programs/programs/20130812/programs__20130812_20130807.tsv._COPYING_

任何建议为什么会发生这种情况？
