Elek, Marton commented on HDFS-12799:
-------------------------------------
Thanks [~vagarychen] the hints:
1. I rebased the patch on top of the latest HDFS-7240. Now it uses HDFS-12793.
(And also uses the latest minicluster)
2. I tried to use the mapping.updateContainer/createContainer, but I can't.
This just manipulates the scm, but I would like to test the communication
between SCM->datanode. So I also need the container creation on the datanode
side, which could be triggered (as I know) by the client with key uploading. So
I kept the original approach in the unit test.

> 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).
