> [snapshot] Ozone fs -ls on snapshot doesn't work for OBJECT_STORE
> -----------------------------------------------------------------
>
> Key: HDDS-7515
> URL: https://issues.apache.org/jira/browse/HDDS-7515
> Project: Apache Ozone
> Issue Type: Task
> Components: Ozone Manager
> Affects Versions: 1.3.0
> Reporter: Soumitra Sulav
> Assignee: Swaminathan Balachandran
> Priority: Major
> Labels: ozone-snapshot
>
> As OBJECT_STORE layout type doesn't support fs ls API, currently listing
> .snapshot isn't supported.
> {code:java}
> ### FILE_SYSTEM_OPTIMIZED
> [root@ozs7b-2 ~]# ozone sh bucket info vol1/fsobuck
> {
> "metadata" : { },
> "volumeName" : "vol1",
> "name" : "fsobuck",
> ..
> "bucketLayout" : "FILE_SYSTEM_OPTIMIZED",
> "owner" : "hdfs",
> "link" : false
> }
> [root@ozs7b-2 ~]# ozone sh key put vol1/fsobuck/key1 anaconda-ks.cfg

> [root@ozs7b-2 ~]# ozone sh snapshot create vol1/fsobuck snap2
> [root@ozs7b-2 ~]# ozone fs -ls ofs://ozone1/vol1/fsobuck/.snapshot/snap2

> ### OBJECT_STORE
> [root@ozs7b-2 ~]# ozone sh bucket info vol1/obsbuck
> {

> "volumeName" : "vol1",
> "name" : "obsbuck",
> ..
> "bucketLayout" : "OBJECT_STORE",

> [root@ozs7b-2 ~]# ozone sh key put vol1/obsbuck/key1 anaconda-ks.cfg
> ..
> [root@ozs7b-2 ~]# ozone fs -ls ofs://ozone1/vol1/obsbuck/.snapshot/snap2
> -ls: Bucket: obsbuck has layout: OBJECT_STORE, which does not support file
> system semantics. Bucket Layout must be FILE_SYSTEM_OPTIMIZED or LEGACY.
> {code}
> Also, we can't list it from the ozone sh key list as these keys aren't listed.
> {code:java}
> [root@ozs7b-2 ~]# ozone sh key list vol1/obsbuck
