Subject [jira] [Commented] (HIVE-14626) Support Trash in Truncate Table
Date Tue, 06 Sep 2016 19:13:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15468260#comment-15468260

Sergio Peña commented on HIVE-14626:
------------------------------------

S3 is treated as another filesystem by Hadoop, and it does not have encryption zones, but
trash may be allowed (but not recommended). Yes, I think you can delete/recreate the directory
on S3. That should work.

> Currently Truncate Table (or Partition) is implemented using FileSystem.delete and then
recreate the directory, so
> 1. it does not support HDFS Trash
> 2. if the table/partition directory is initially encryption protected, after being deleted
and recreated, it is no more protected.
> The new implementation is to clean the contents of directory using multi-threaded trashFiles.
If Trash is enabled and has a lower encryption level than the data directory, the files under
it will be deleted. Otherwise, they will be Trashed
