Steve Loughran commented on HDFS-14200: --------------------------------------- seems good, but the patch isn't ready yet. * Why not just add an option to -expunge. It exists, has tests, documentation, etc? * add a way to take a filesystem so that I can do this for s3a://bucket1/ . See HADOOP-13656 * TestTrash:L509. Dont downgrade an exception to a log, just rethrow Finally: press the submit button so yetus runs it. No yetus, no review. > Add emptyTrash option to purge trash immediately > ------------------------------------------------ > > Key: HDFS-14200 > URL: https://issues.apache.org/jira/browse/HDFS-14200 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Reporter: Stephen O'Donnell > Assignee: Stephen O'Donnell > Priority: Major > Attachments: HDFS-14200.001.patch > > > I have always felt the HDFS trash is missing a simple way to empty the > current users trash immediately. We have "expunge" but in my experience > supporting clusters, end users find this confusing. When most end users run > expunge, they really want to empty their trash immediately and get confused > when expunge does not do this. > This can result in users performing somewhat dangerous "skipTrash" operations > on the trash to free up space. The alternative, which most users will not > figure out on their own is: > # Run the expunge command once - this will move the current folder to a > checkpoint and remove any old checkpoints older than the retention interval > # Wait over 1 minute and then run expunge again, overriding fs.trash.interval > to 1 minute using the following command hadoop fs -Dfs.trash.interval=1 > -expunge. > With this Jira I am proposing to add a extra command, "hdfs dfs -emptyTrash" > that purges everything in the logged in users Trash directories immediately. > How would the community feel about adding this new option? I will upload a > patch for comments. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
