Weiwei Yang updated HDFS-11716:
-------------------------------
Description: Current delete container API seems can be possibly running
into inconsistent state. SCM maintains a mapping of container to nodes,
datanode maintains the actual container's data. When deletes a container, we
need to make sure db is removed as well as the mapping in SCM also gets
updated. What if the datanode failed to remove stuff for a container, do we
update the mapping? We need to revisit the implementation and get these issues
addressed. See more discussion
