-------------------------------------
Hi [~msingh],
Found the following behavior with ozone fs.
# When we put a key with keyName ending with a slash, the trailing slash is
removed.
{code:java}
$ ./ozone sh key put volume/bucket/testKey3/ /etc/services -r=ONE
$ ./ozone sh key list volume/bucket
[ {
"version" : 0,
"md5hash" : null,
"createdOn" : "Tue, 25 Sep 2018 20:40:41 GMT",
"modifiedOn" : "Tue, 25 Sep 2018 21:12:57 GMT",
"size" : 677972,
"keyName" : "testKey3"
} ]{code}
# Sub-folders of a directory are not listed if we there is a key present with
the same name without trailing slash.
{code:java}
# There is a key "testKey2" and a directory "testKey2/" under the root folder /.
$ bin ./ozone fs -ls /
-rw-rw-rw- 1 5253 2018-09-25 13:16 /testKey2
drwxrwxrwx - 0 2018-09-25 11:26 /testKey2
# Directory and its subfolders are not listed, only the key is listed
$ ./ozone fs -ls /testKey2/
-rw-rw-rw- 1 5253 2018-09-25 13:16 /testKey2
# If no key is present with the same name as the directory, the subfolders are
listed
$ ./ozone fs -ls /testKey2/subKey2_1
drwxrwxrwx - 0 2018-09-25 13:13 /testKey2/subKey2_1/subsubKey2_1_1{code}
I think we should have a consistent behavior when listing files/ folders.
