Weiwei Yang updated HADOOP-13686:
---------------------------------
Attachment: HADOOP-13686.01.patch
Added following tests
# {{testCheckpointInterval}} this test sets multiple values (legal and illegal)
to *fs.trash.checkpoint.interval* and verify the values are set in emptier as
expected.
# {{testTrashPermission}} this test verifies when files moved to trash, file
permission is reserved. And user is able to remove their own trash directory.
# {{testMoveEmptyDirToTrash}} this test user is able to move an empty directory
to trash.
# {{testTrashRestarts}} this tests simulates a restart of the parent process
(NN), verifies *fs.trash.interval* is honoured during restart.
Some more things
bq. 3. test fs.trash.interval with invalid values such as 0 or negative
This is already covered so it's not in this patch. {{TestTrash#trashShell}}
tested setting value to 0. {{TestStateTransitionFailure}} tested setting a
negative value. Namenode will not be started with error "Cannot start trash
emptier with negative interval. Set fs.trash.interval to a positive value".
And this patch fixed an issue that setting a negative value to
fs.trash.checkpoint.interval is not handled in {{TrashPolicyDefault}}.
