Shilun Fan updated HDFS-15513:
------------------------------
    Target Version/s: 3.5.0  (was: 3.4.1)

> Allow client to query snapshot status on one directory
> ------------------------------------------------------
>
>                 Key: HDFS-15513
>                 URL: https://issues.apache.org/jira/browse/HDFS-15513
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: hdfs, hdfs-client
>    Affects Versions: 3.3.0
>            Reporter: Siyao Meng
>            Priority: Major
>
> Alternatively, we can allow the client to query snapshot status on *a list 
> of* given directories by the client. Thoughts?
> Rationale:
> At the moment, we could only retrieve the full list of snapshottable 
> directories with 
> [{{getSnapshottableDirListing()}}|https://github.com/apache/hadoop/blob/233619a0a462ae2eb7e7253b6bb8ae48eaa5eb19/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSNamesystem.java#L6986-L6994].
>  This leads to the inefficiency In HDFS-15492 that we have to get the 
> *entire* list of snapshottable directory to check if a file being deleted is 
> inside a snapshottable directory.
