John Vines created HDFS-4683:
--------------------------------
Summary: Per directory trash settings / trash override
Key: HDFS-4683
URL: https://issues.apache.org/jira/browse/HDFS-4683
Project: Hadoop HDFS
Issue Type: Improvement
Environment: Hadoop2
Reporter: John Vines
With the migration of trash settings to server side, it becomes more
complicated for applications built on top of HDFS to properly deal with their
trash. Applications like HBase and Accumulo already have a fair amount of trash
management, adding the HDFS Trash will simply put more stress on DFS. But fully
disabling the trash is overkill, as there still may be use for it in other uses
of hadoop.
I would like to request either:
A. per directory or user trash settings, so that applications which work in a
specific directory or use a specific user can continue to ignore the trash.
B. An updated DistributedFileSystem delete() call which allows you to force
ignoring the trash. I'm not sure how feasible this is due to the FileSystem
API, but it may be possible.
