Chen Liang commented on HDFS-12799:
-----------------------------------

Thanks for working on this [~elek]. Returning current state does seem to be a 
bug and was causing test failing. So I fixed it in HDFS-12793. As for creating 
container, have you tried to call 
{{cluster.getStorageContainerManager().allocateContainer}}, followed with two 
{{mapping.updateContainerState}}, just like what 
{{TestContainerMapping#createContainer}} is doing?

> This issue is about extending the HB response protocol between SCM and DN 
> with a command to ask the datanode to close a container. (This is just about 
> extending the protocol not about fixing the implementation of SCM tto handle 
> the state transitions).
