Hi Artem, right now HDFS has a trash functionality that moves files removed with 'hadoop dfs -rm' to an intermediate directory (/trash). You can configure how may time a file spends in that directory before it's actually removed from the filesystem. Look for 'fs.trash.interval' on your hdfs-site.xml or configuration guide . You can force trash clean up with 'hdfs dfs -expunge'.
