{quote}Also, this patch won't work with security enabled since the NN's handler
does not have any credentials.

[~daryn] It works in secure environment because authentication token will send
to Webhdfs server, where we do doAs with this credentials. Tested this patch
in Secure cluster.
NamenodeWebHdfsMethods#delete
{code:java}
return doAs(ugi, new PrivilegedExceptionAction<Response>() {
@Override
public Response run() throws IOException {
return delete(ugi, delegation, username, doAsUser,
path.getAbsolutePath(), op, recursive, skiptrash, snapshotName);
}
{code}
Btw, yes I should not use Filesystem object, will use direct rename(trash)
call to Namenode.

> Files/Directories deleted via webhdfs rest call doesn't use the skiptrash
> feature, it would be deleted permanently. This feature is very important us
> because our user has deleted large directory accidentally.
> By default, Skiptrash option is set to true, skiptrash=true. Any files, Using
> CURL will be permanently deleted.
> Example:
> curl -iv -X DELETE
> "http://xxxx:50070/webhdfs/v1/tmp/sampledata?op=DELETE&user.name=hdfs&recursive=true";
>
> Use skiptrash=false, to move files to trash Instead.
> Example:
> curl -iv -X DELETE
> "http://xxxx:50070/webhdfs/v1/tmp/sampledata?op=DELETE&user.name=hdfs&recursive=true&skiptrash=false";
