Review Comment:
It seems better to make it a client side conf. We may add a new
ContainerProtos.Type, say StreamInitWithPutBlock and set it in the following
line:
-
https://github.com/apache/ozone/blob/398709d6b68312306149144795c5796d4d3fa8b3/hadoop-hdds/client/src/main/java/org/apache/hadoop/hdds/scm/storage/BlockDataStreamOutput.java#L216
