/**
* Asynchronously register a partition and its producer with the
shuffle service.
*
+ * <p>IMPORTANT: Please implement the asynchronous interface in a
synchronous way.
+ * The default scheduler only supports synchronous registration for now.
+ * Please refer to {@link
NettyShuffleMaster#registerPartitionWithProducer} for example.
Review comment:
I'd prefer to state that "one must return a completed future at the moment".
It is clear enough so the user do need to refer to NettyShuffleMaster for the
implementation.
