Anu Engineer commented on HDFS-12195:
-------------------------------------
[~yuanbo] Thank you for updating the patch. It looks quite good, I have 2 nits,
I think we can commit this after those are addressed.
*KeyManager.java*
{code}
List<KsmKeyInfo> listKeys(String keyPrefix, int maxKeys)
throws IOException;
{code}
* Key Manager contains API's needed by the client. While I agree that this is
needed by you, I don't think this should be part of KeyManager.
* please rename FAILED_KEY_NOT_FOUND ==> KEY_NOT_FOUND
> Ozone: DeleteKey-1: KSM replies delete key request asynchronously

> We will implement delete key in ozone in multiple child tasks, this is 1 of
> the child task to implement client to scm communication. We need to do it in
> async manner, once key state is changed in ksm metadata, ksm is ready to
> reply client with a successful message. Actual deletes on other layers will
> happen some time later.
