在HDFS中删除某个文件/目录时是否有可能收到通知？

I want to get a notification when a certain file/ directory has been deleted in HDFS. It would also be possible to generate a kind of log file with timestamp, affected file/ directory and so on. I need this due to traceability requirements.

我希望在HDFS中删除某个文件/目录时收到通知。还可以生成一种带有时间戳,受影响的文件/目录等的日志文件。由于可追溯性要求,我需要这个。

Is there any script, software et cetera to cover this kind of task?

是否有任何脚本,软件等来涵盖这类任务?

Use HdfsAdmin.getInotifyEventStream(...) to open an DFSInotifyEventInputStream. Monitor the events in the stream for an event of type Event.UnlinkEvent.
