Hello! I'm using the hadoop version from cloudera hadoop-core-0.20.2-cdh3u1-SNAPSHOT.jar. Today I've made a mistake. I have deleted my user from HDFS with the command hadoop fs -rmr /user/my_user
No question: are you sure to delete? Are you really sure? So panic...what to do? How can I recover my lost data? From the above real scenario, the following improvements and questions can incur: 1. Add a question when you are deleting a folder or a file, such as "Are you sure you want to delete X?" 2. In order to automate the delete process and surpass the above question, add an option to pass the answer to it (sometimes you need this feature) 3. How can recover a deleted "user" with its associated data (in my case "my_user") 4. Where goes the data from a deleted folder with the "rmr" otion? 5. Where goes the data from a deleted folder with the "rm" otion? 6. How can be recovered (undeleted) the data deleted from question 4 and 5? Thank you for your answers. Kind regards, Florin
