----------------------------------

             Summary: Support Trash in Truncate Table
                 Key: HIVE-14626
                 URL: https://issues.apache.org/jira/browse/HIVE-14626
             Project: Hive
          Issue Type: Sub-task
          Components: Query Processor
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang
            Priority: Minor


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
