-------------------------------------
Thanks for the review [~mackrorysd]!
I think we should handle this case otherwise, like throwing an error if no
prefix specified at all. A prefix (default "/" prefix as well) should be
specified to run this command.
The other way would be to use something like this:
{code:java}
String keyPrefix = "/";
if(paths.get(0).length() == 0) {
Path path = new Path(paths.get(0));
keyPrefix = PathMetadataDynamoDBTranslation.pathToParentKey(path);
}
getStore().prune(divide, keyPrefix);
{code}
> S3GuardTool prune to prune specific bucket entries

> Users may think that when you provide a URI to a bucket, you are pruning all
> entries in the table *for that bucket*. In fact you are purging all entries
> across all buckets in the table:
> {code}
> hadoop s3guard prune -days 7 s3a://ireland-1
> {code}
> It should be restricted to that bucket, unless you specify otherwise
> +maybe also add a hard date rather than a relative one
